Cheers, Eugen. Simply put, a lock is a more flexible and sophisticated thread synchronization mechanism than the standard synchronized block. The Lock interface has been around since Java 1. It's defined inside the java. In this article, we'll explore different implementations of the Lock interface metal cabinet locking mechanism java their applications.

There are few differences between the use of synchronized block and using Lock API's:. A locked instance should always be unlocked to avoid deadlock condition. In addition to the Lock interfacewe have metal cabinet locking mechanism java ReadWriteLock interface which maintains a pair of locks, one for read-only operations, and one for the write operation.

The read lock may be simultaneously held by multiple threads as long as there is no write. ReentrantLock class implements the Lock interface. It offers the same concurrency and memory semantics, as the implicit monitor lock accessed using synchronized methods and statements, with extended capabilities. We need to make sure that we are wrapping the lock and the unlock calls in the try-finally block to avoid the deadlock situations.

In this case, the thread calling tryLockwill wait for one second and will give up waiting if the lock isn't available. For both the write methods, we need to surround the critical section with the write lock, only one thread can get access to it:. For both read methods, we need to surround the critical section with the read lock. Multiple threads can get access to this section if no write operation is in progress. StampedLock is introduced in Java 8. It also supports both read and write locks.

However, lock acquisition methods return a stamp that is used to release a lock or to check if the lock is still valid:. Another feature provided by StampedLock is metal cabinet locking mechanism java locking. Most of the time read operations don't need to wait for write operation completion and as a result of this, the full-fledged read lock isn't required.

The Condition class provides the ability for a thread to wait for some condition to occur while executing the critical section. This can occur when a thread metal cabinet locking mechanism java the access to the critical section but doesn't have the necessary condition to perform its operation.

For example, a reader thread can get access to the lock of a shared queue, which still doesn't have any data to consume. Traditionally Java provides waitnotify and notifyAll methods for thread intercommunication. Conditions have similar mechanisms, but in addition, we can specify multiple conditions:. In this article, we have seen different implementations of the Lock interface and the newly introduced StampedLock class.

We metal cabinet locking mechanism java explored how we can make use of the Condition class to work with multiple conditions. The complete code for this tutorial is available over on GitHub.

What is a Lock Mechanism? A. lock mechanism. is the assembly of parts inside a lock that makes it work. In most common locks, the locking mecha-nism holds or moves a latch, bolt, or shackle into the locked or unlocked position. Due to the many types of lock designs, there are many different types of locking mechanisms. Oct 01,  · Let me explain how this mechanism works. When a thread enters line 1, it attempts to acquire the lock object and if the lock is not held by another thread, the current thread gets exclusive ownership on the lock object. If the lock is currently held by another thread, then the current thread blocks and waits until the lock is released.
