Visiting the physical branches of banks is not only time consuming but can also be hectic, thanks to long queues and waiting time. Not to forget, running to banks for every minor banking task creates an unnecessary burden on bank staff. These issues can be addressed by developing an online banking system that will offer seamless and prompt banking services to customers. However, to use this software application, a user must be registered with the system.
To do so, the user has to create a unique user name and password for securely logging in to the application. This online bank management application will provide the following services to customers:.
This is another web-based Java project that is designed to create a direct line of communication between doctors and patients. The application also lets users look for and connect with blood and eye donors. This is one of the excellent java project ideas for the current time. In conventional healthcare service systems, all medical management operations are manual.
The problem is more pronounced in remote and rural areas that lack proper medical infrastructure, qualified healthcare professionals, and sophisticated medical equipment. Furthermore, there are no provisions for recording and storing medical data.
This online medical management system can help bridge all these problems by linking doctors and patients directly. The application has two modules — an Admin module and a Doctor module.
The Admin module manages the online software system, and the Doctor module allows doctors to interact with patients. Anyone can access the services provided by this app from any location via the Internet. One of the best ideas to start experimenting you hands-on Java projects for students is working on online quiz management. This Java-based application proposes to create an online discussion platform that will consist of a wide range of questions on different topics, fields, and subjects.
By creating a user-friendly environment of Bluebook implementation, this application is a resourceful tool for individuals who wish to practice mock quizzes and tests. Online quiz management system is one of the interesting java projects.
In this project, you will build a comprehensive online platform for managing both quiz competitions and the participants in the different teams. This application can be used by academic institutions and any organization willing to find suitable candidates through the process of quizzing. The application permits multiple admins, each having their unique user id and password.
All the participants will automatically receive the questions, and the teams will have to answer within an allotted time. The teams having the lowest average score will be eliminated, and the remaining teams will continue to compete in the next level. This will continue until the winner is declared.
The scores for each team will be automatically updated. And this is the perfect idea for your next Java project! This is a project for developing an online survey system using Java as the foundation. The focus of the project is to build an online platform that can efficiently collect the viewpoints of the target audience of a survey via the Internet. This application can launch online surveys and also send email notifications.
Any organization in any industry can use this application to conduct online surveys for obtaining necessary information from their target audience groups. In this survey application, only the users authenticated by the Admin can cast their vote and express their opinion on a particular issue or topic. Once the users submit the votes, the software will collect this using the ratio button or checkbox. It will then automatically add the votes to each alternative and display the result after the deadline of the survey.
Since the survey is conducted online, it eliminates several hours of manual labor, along with a significant reduction in survey costs. It allows the retrieval of the latest content posted on a website quickly on the aggregator, thus, making the content readily accessible to the users for reading. The existing aggregator management applications use the homogeneous Poisson model that relies on a specific data source either a webpage or RSS feed.
As a result, these applications cannot adapt if the data source changes. They do not even have well-designed monitoring policies. This project incorporates and implements new content monitoring strategies to overcome the drawbacks of the existing aggregator management applications.
The new RSS feed reader leverages a non-homogeneous Poisson model and delay matrices. This RSS feed reader management system investigates the techniques used by RSS aggregation services to monitor web content and to retrieve the data promptly using minimal resources, to enable readers to access the content without delay. The project focuses mainly on the server-based aggregation scenario.
The Smart City project is a web-based software application built to store all the essential details of a city. Cities and urban areas witness a massive wave of people coming from every corner in search of jobs, education, and even a better lifestyle.
The smart city project seeks to address that by creating an integrated platform to store essential and related information to guide the newcomers in a city. The application will provide visitors, students, and job seekers information like hotels, renting facilities, transportation services, healthcare services, airline ticket booking, shopping landmarks, emergency helpline, and basically every information that one needs when in a new city.
It is like a smart city guide for visitors. Users can connect to the application via the Internet and browse all the smart city web pages to get the details they need.
Users can see the entire map of a city along with the important landmarks. This will make their movement across the city much more comfortable. Mentioning java projects can help your resume look much more interesting than others.
This is one of the trending Java projects. This web-based Java application is designed to manage stocks for companies and organizations and also handle the sale and purchase of their products. The stock management system includes different modules and features for adding, editing, viewing, and deleting items in the system database.
Usually, the manual stock management method run with pen and paper is not only labor-intensive but also time-consuming. This approach lacks a proper data organization structure, which can give rise to many risks associated with data mismanagement. This stock management project is a more efficient and improved approach to stock data management.
It is much more secure and reliable than the manual method. In the application, the login page makes the system module. The Admin can use this module to log in to the system through a valid user ID and password. Once logged in, the Admin can control these features:. The Admin can update and monitor all necessary information associated with stock management, including category, customer details, stock details, stock purchase, stock sales, stock entries, stock entries payments, stock sales payments, supplier details, etc.
The application further includes other functions like printing payment receipts, view purchase reports and sales reports, and so on. This is one of the interesting Java projects. Supply chain management refers to the management of businesses interconnected over a network. Each of these subnodes also has a context menu of commands. In the Projects , Files , and Favorites windows, an Ant script's subnodes are flagged in the following ways:.
Emphasized Ant target. These targets include a description attribute, which is displayed as a tooltip. You define the target's description attribute in the Source Editor.
Double-click any of the Ant script's subnodes to jump to that target's location in the Source Editor. All of the normal XML search tools, selection tools, and keyboard shortcuts are available for editing Ant scripts, and the IDE provides code completion for all standard Ant tasks.
When you create a target that you want to run from the command line, give the target a description attribute. With this command, Ant lists only those targets that have a description attribute, together with their descriptions.
Especially when there are many targets in your Ant build script, emphasizing some and de-emphasizing others can be a useful way to distinguish between those that you use a lot and those that you use less often. The font style of a subnode's label in the Projects, Files, and Favorites windows indicates the following:.
Greyed out. An internal target that cannot be run directly. Internal targets have names beginning with -. The default target for the script, if there is one. The default target is declared as an attribute of the project, together with other project attributes, such as its name.
You define the project's default attribute in the Source Editor. Targets that are imported from another script but are overridden in the importing script are not listed. Only the overriding target is listed. You can use custom Ant tasks to expand on the functionality provided by Ant's built-in tasks. Custom tasks are often used to define properties, create nested elements, or write text directly between tags using the addText method.
Select the Other category and the Custom Ant Task file type. When you create the custom Ant task file, the template opens in the Source Editor. The template contains sample code for many of the common operations performed by Ant tasks. After each section of code, the template also shows you how to use the task in an Ant script. The IDE runs targets in your project's Ant script any time you run commands on your project. You can also manually run a target in any Ant script from the Ant script's node in the Files window or Favorites window.
Right-click the Ant script node and choose the target you want to run from the Run Target submenu. Choose Other Targets to run a target that has not been emphasized with a description attribute. Internal targets are excluded from these lists because they cannot be run independently.
Select the Ant script node to display its targets in the Navigator window. Then right-click the target node and choose Run Target. The Output window displays compilation errors generated by Ant scripts as normal Java code compilation errors.
You can double-click any error message to jump to the location in the source where the error occurred. For more information, see Section 5. Debugging an Ant script is handy when you need to diagnose a problem in the Ant script's execution or examine how the script works.
Right-click the Ant script node in the Projects window, Files window, or Favorites window and choose any target from the Debug Target menu. When you start debugging an Ant script, the IDE opens the Debugger windows, goes to the first line of the target, and stops. You can perform all of the following operations:.
Set a line breakpoint by clicking in the Source Editor's left margin and use the Continue F5 command to run the Ant script to the line.
You can create a mini-script that serves as a shortcut to a commonly used target in an Ant script. You can also customize the way the target is run. The shortcut can be saved as a menu item, toolbar button, or keyboard shortcut. Select the build script node in the Files or Favorites window to display its targets in the Navigation window.
Specify where you want to place the shortcut and whether you want to customize its Ant code and click Next. Use the remaining pages of the wizard to assign the shortcut to a toolbar, menu, or keyboard shortcut.
The wizard only shows those steps that you selected in Step 3. In the Customize Script page, add or change any of the shortcut script's elements, such as tasks or properties. This page only appears if you selected the Customize generated Ant code checkbox in Step 3. When you have specified all of the necessary information, click Finish.
The shortcut is created in the specified locations. Ant Home. Displays the installation directory of the Ant executable used by the IDE. You can change Ant versions by typing the full path to a new Ant installation directory in this property. You can only switch between versions 1. For example, for the standard Ant 1. If you enter a directory that does not match this structure, the IDE gives you an error. Save Files. If selected, saves all unsaved files in the IDE before running Ant.
It is recommended to leave this property selected because modifications to files in the IDE are not recognized by Ant unless they are first saved to disk. Verbosity Level. Sets the amount of compilation output. You can set the verbosity lower to suppress informational messages or higher to get more detailed information. Always Show Output. If selected, fronts the Output window tab if the Ant output requires user input or contains a hyperlink.
Output that contains hyperlinks usually denotes an error or warning. Reuse Output Tabs. If selected, writes Ant output to a single Output window tab, deleting the output from the previous process. If not selected, opens a new tab for each Ant process. Configures custom properties to pass to an Ant script each time you call Ant.
Click the ellipsis button to open the property editor. If you are compiling using Jikes build. It is recommended that you leave this property set to true even if you are not using Jikes, since the IDE prefers Emacs-compatible error messages. Contains binaries and libraries that are added to Ant's classpath. The IDE comes bundled with Ant version 1. Click Miscellaneous in the left panel of the window and expand the Ant node. The Ant Home section displays the current Ant location and version.
For your build script to use custom tasks, you must add the tasks to Ant's classpath in the IDE. To add custom tasks to Ant's classpath within the IDE:. If you cannot declare a classpath in your build script, or you are using third-party build scripts that you cannot alter, you can add the tasks to Ant's classpath in the IDE. Open the Options window, click Miscellaneous in the left panel of the window, and expand the Ant node.
Use the Classpath section to manage the Ant classpath. Only add items to the Ant classpath that are needed to run custom tasks. Do not use the Classpath settings to manage the compilation or runtime classpath of your project source folders.
For information on managing the project classpath, see Chapter 5, "Managing the Classpath. Using an explicit classpath is the recommended method as it ensures that your build scripts are fully portable.
You can write your tasks and include instructions to compile them and produce a JAR file in the build file. To use these tasks, include the long form of taskdef , which includes a classpath. Here is a simple example of such a task:.
Example Sample of a Task with an Explicit Classpath. The advantage of this method is that no special preparation is needed to begin using the script. The script is entirely self-contained and portable. This method also makes it easier to develop your tasks within the IDE as the script compiles them for you automatically. To make the your build scripts even more robust, use a property instead of a hard-coded location to specify the classpath to your tasks.
You can store the property in the build script itself or in a separate ant. You can then change the classpath setting throughout your script by simply changing the value of the specified property. Select the Available Plugins tab and locate the Ant documentation plugin. Select the Install checkbox for the Ant documentation plugin and click Install. Click the Proxy Settings button in the Settings tab of the Plugin manager and set make sure the proxy settings are correct.
Click OK and try to connect to the update center again. The official release of the Ant documentation plugin does not always coincide with the release of the IDE. Before building a project, set the compilation classpath for details, see Section 5. Build errors are displayed in the IDE's Output window. Once all errors in the code have been corrected, clean the build and dist directories by deleting their contents. You can examine the build output by viewing compiled classes in the project's build directory and the Javadoc files and built libraries, such as JAR and WAR files, in the project's dist directory from the Files window.
When you build a project, the IDE calls the corresponding target in the project's Ant build script. You can build a project and all of its required projects, or build any project individually. You do not need to build the project or compile individual classes to run the project in the IDE.
By default, the IDE automatically compiles classes when you save them. These incrementally compiled files are stored in a cache in your user directory and are copied to your project's build folder when you run or debug your project.
This incremental compilation can save you a lot of time when you are editing and testing your project. However, you need to build the project to generate distributable files for the project, such as JAR files. By default, the Build Project command is Projects To Build In Javascript Error Occurred not enabled since most of that command's functions are handled by the incremental compilation.
However, you can use the Clean and Build command to create a fresh build. When you clean and build a project, all previous build outputs are deleted and new versions of the build outputs are created.
To build a project and its required projects:. Alternatively, right-click the project's node in the Projects window and choose Clean and Build. Double-click any error to go to the location in the source code where the error occurred.
Keyboard shortcuts for Debug and Profile also apply to the main project. To turn off incremental compilation for a project:. You can compile individual files as well entire project files. For information on compiling individual files, see Section 7. If you need to modify the main class or specify runtime arguments, see Section 9.
The IDE supports creating and starting build jobs using the Hudson build server. Hudson is an open-source server that you can use to build your applications. You can use the Hudson server as part of your continuous integration CI process for automated building, verification and testing. After you add a Hudson instance, a node for the instance is added below the Hudson Builders node.
You can expand the node to view the status of builds on that instance. You can specify the application that you want the server to build by creating a new build. When you create the build, you specify the repository containing the sources for the application. A node for the build is added under the node of the target Hudson instance in the Services window. To view additional details about the status of builds, right-click the node for the build and choose Open in Browser.
Alternatively, in the Services window, right-click the Hudson instance you want to use and choose New Build. After you supply the details for the build, you can start the build process on the server by right-clicking the build that you want to start and choosing Start Job.
When a job is building, the node for the job is displayed as running. You can expand the node for the job to view past builds and build artifacts. By default, you do not need to manually compile the files to run your application in the IDE. Files in a standard Java project are compiled automatically when you save the files.
If you have turned off the Compile on Save feature for a project, you can compile files by building the project or by compiling individual files.
If you are using a free-form project, you need an Ant target for this command. The IDE offers to generate a target the first time you choose the command. In the generated target, specify the directory where to put the compiled class. You can do so by specifying a value for the build. Alternatively, you can replace the value of the provided build.
For information on managing the classpath, see Section 5. The JAR file is generated to the dist directory of your project folder. The default filter does this for you by excluding all. In addition to the default expressions, you can create additional filters using regular expressions to control the output files.
To specify which files are added to the JAR file:. To disable generation of a JAR file for a project:. Alternatively, if you deselect the Build JAR after Compiling option in the Packaging category of the Properties window the Java compiler will produce only.
See Section 5. For information on customizing an Ant build script, see Section 5. A native package is a wrapper for your project that turns the project into a self-contained, platform-specific installation package. It enables your project to be packaged with the Java runtime to produce an installer that is common for the operating system you are working in.
Due to the inclusion of the Java runtime JavaFX runtime for JavaFX applications , the size of the application is significantly larger than a standard packaged application.
Application formats are platform-specific to create a bundle for different operating systems, you must build your project on each platform. Note that native packaging might require external tools. For instance, if you want to package a Java application to distribute to a non-Windows environment, you need the appbundler tool, which is not included in JDK7update 6. The html file defines how the applet is embedded in the web page.
To enable native packaging actions in the project context menu:. Right-click the project node in the Projects window and select Properties from the context menu. A Package as command is added to the project's context menu. When you are ready to package your application, right-click the project, choose Package as, and select one of the packaging types:. All Artifacts - Creates a package that contains only the project artifacts.
All Installers - Creates a package that contains the application image and all applicable installers. Image Only - Creates a package that contains the application image only.
When you select a packaging type, a subdirectory is created under the project's dist directory where the package is stored. Be aware that the packaging process can take some time to complete and, depending on the tools you are using, progress might not be indicated.
Note that the contents of the submenu are dependent on the operating system you are running on. If you added a folder of classes or resources to the classpath as opposed to a JAR file or project , none of the classpath elements are copied to the dist folder.
If a library on the project's classpath also has a Class-Path element specified in its manifest, the content of the Class-Path element must be on the project's runtime path.
Once you have distributed the archive of your application, the application can be run outside of the IDE from the command line. To run an application JAR file from the command line:. When you run the jar command, the JAR tool uses the JAR manifest to determine the application entry point and the paths to the dependent binaries that are specified in the manifest.
The Output window is a multi-tabbed window that displays messages from the IDE. This window is displayed automatically when you encounter compilation errors, debug your program, generate Javadoc documentation, and so on.
One function of the Output window is to notify you of errors found while compiling your program. The error message is displayed in blue underlined text and is linked to the line in the source code that caused the error.
The Output window also provides links to errors found when running Ant build scripts and when checking and validating XML documents.
For information on validating XML documents, see Section If the file that contains the error is open, the Source Editor jumps to the line containing each error as you move the insertion point into the error in the Source Editor. Every action that is run by an Ant script, such as compiling, running, and debugging files, sends its output to the same Output window tab.
If you need to save some output, you can copy and paste it to a separate file. To set Ant to print the command output for each new target to a new Output window tab:.
Click Miscellaneous in the left panel of the window, expand the Ant node, and select the checkbox in the Reuse Output Tabs property. When you run a program that requires user input, a new tab appears in the Output window. This tab includes a cursor. You can enter information in the Output window as you would on a command line. Refactoring is the use of small transformations to restructure code without changing any program behavior.
Just as you factor an expression to make it easier to understand or modify, you refactor code to make it easier to read, simpler to understand, and faster to update.
And just as a refactored expression must produce the same result, the refactored program must be functionally equivalent with the original source. The IDE's refactoring features simplify code restructuring by evaluating the changes that you want to make, showing you the parts of your application that are affected, and making all necessary changes to your code.
For example, if you use the Rename operation to change a class name, the IDE finds every usage of that name in your code and offers to change each occurrence of that name for you. For information on how to refactor an Enterprise Bean, see Section 7. You can undo any changes that you made using the commands in the Refactor menu.
When you undo a refactoring, the IDE rolls back all the changes in all the files that were affected by the refactoring. If any of the affected files have been modified since the refactoring took place, the Refactoring Undo is not available. Use the Find Usages command to determine everywhere a class, method, or field is used in your project's source code. To find where a class, interface, method, or field is used in your project:.
To jump to a specific occurrence of the code element:. For classes and interfaces, the Find Usages command displays all the code lines that:. Use the type, such as creating a new instance, importing, extending, implementing, casting, or throwing. After you choose the Find Usages command on a class or interface, the Find Usages dialog box might give you additional options:.
Find All Subtypes checkbox. If selected, only usages of subtypes of the class are displayed. Find Direct Subtypes Only checkbox. If selected, only usages of direct subtypes are displayed. Subtypes of those subtypes are ignored. After you choose the Find Usages command on a method, the Find Usages dialog box might give you additional options:.
Include overloaded methods checkbox. If selected, any occurrences of overloaded methods are displayed. Search from Base Class checkbox. If selected, the output shows every usage of that base method. This option only appears if the method that you are finding usages for overrides another method. Other IDE tools that enable you to search for all the places where specific text is used in a project include:. Finding and Replacing Text.
Searches for all the places where specific text is used in a source file that is open in the Java Editor. These commands finds all matching strings, regardless of whether the string is a Java element. Find in Projects. As with the Find command, the Find in Projects command searches for matching strings, regardless of whether the string is a class name. To find where a method is declared in a source file, you can either double-click the method in the Projects window or Navigator window.
Use the refactoring Rename command to rename a class or interface. When you rename a class or interface through refactoring, all instances of that class or interface are renamed throughout the project. If you do not want to enact a global change, you can simply select the desired class or interface and edit its name. To rename a class or interface and update references to it throughout your project:. In the Refactoring window, review the lines of code that are affected by the change and clear the checkbox of any code that you do not want changed.
Always perform a clean build after completing any refactoring commands. Clean a build by right-clicking the project's node in the Projects window and choosing Clean and Build Project. To rename the class or interface without refactoring:. You can rename a class this way by selecting the node of the class and then pressing F2 to make the name editable. In the Rename dialog box, select the Rename Without Refactoring checkbox. If you need to back out a refactoring change, see Section 7.
Use the refactoring Rename command to rename a field or method. As with renaming a class or interface, the scope of a renaming operation is the full scope of the element in the project.
Field and method usages are replaced everywhere they appear in the project. Parameters and variables are renamed only in the lexical scope of their definitions. Other elements with the same name are not modified. To rename a field or method and update references to it throughout your project:.
Optional Click Preview. In the Refactoring window, at the bottom of the Source Editor, review the lines of code that are affected by the change and clear the checkbox of any code that you do not want changed. Type the new name. Press Escape to finish renaming.
You can do a clean build by right-clicking the project's node in the Projects window and choosing Clean and Build Project.
For information on how to undo refactoring, see Section 7. Use the refactoring Move command to move a class to another package.
All references to the class are updated the next time you build the project. To move a class to another package and to change the code that references that class:. In the Move Class dialog box, select the package from the To Package drop-down list or type the fully qualified package name, such as com. If you click Refactor , the IDE applies the changes automatically and skips the remaining steps. If you click Preview , the Refactoring window displays the lines of code that are affected.
Review the list and clear the checkbox of any code that you do not want changed. If the class that you are pushing members from has multiple subclasses and you do not want the members to be pushed to all of them, be sure to clear the checkboxes for the corresponding subclasses.
Click Do Refactoring to apply the selected changes. You can also initiate the moving of a class by dragging a class's node in the Projects window to another package's node or by cutting and pasting a class's node.
You can also use the Move command to move the methods and fields of a selected class to another package. In the Move Members dialog box, select the package from the drop-down list or type the fully qualified package name, such as com. Check the option if you want to keep the original method signatures in the source class and let them call the new methods in the target class.
Use the Move Inner to Outer Level command to do move an inner class one level up in hierarchy. For example, if the selected class is directly nested in a top-level class, a new top-level class is created.
If the selected class is nested in an inner class, the selected class is moved to the level of the inner class in which it was nested.
To use the Move Inner to Outer Level operation:. Optional Select the Declare Field for the Current Outer Class checkbox if you want to generate an instance field for the current outer class and pass the outer class to the constructor.
If you select this checkbox, type a name for the outer class' instance field. Use the Pull Up command to move methods and fields to a class that their current class inherits from. In the Source Editor or Projects window, select the class that contains members that you want to move. The Pull Up dialog box appears and displays a list of the class's members and any interfaces that the class implements.
In the Destination Supertype drop-down list, select the class to which you want to move the members. If the current class implements any interfaces, there are checkboxes for these interfaces. If you select a checkbox for an interface, the implements statement for that interface is moved to the superclass. Optional If you want to make a method abstract, select the Make Abstract checkbox for the method.
If you select this checkbox, the method will be declared in the superclass as an abstract method and overridden in the current class. The method will be assigned the protected access modifier. Use the Push Down command to move inner classes, methods, and fields to all subclasses of their current class.
In the Source Editor or Projects window, select the class member or class members that you want to move. In addition, it will be able to operate by searching the web using three search engines and enlists 25 best links. This project will teach you how to code with simple email operations, for example, setting the mailbox capacity, setting the alternate email, changing the password, and many more.
The idea behind this project is to bring about the implementation of a money management system for schools. The idea behind this project is the creation of the classical snake game in Java.
Beginners will definitely not spend too much time in making this program happen. This project is simply a console dependent application and it comes in five different types. For example, it includes account holder, account, bank transaction, bank, and specific ATM of the bank.
As you can see there are nice easy projects in Java you can lay your hands-on while you continue improving to become a professional programmer in Java programming language. The examples explained in this article are the best project for you as a beginner trying to figure out Java.
