What is Lock interface in Java Concurrency API?

A lock is a thread synchronization mechanism like synchronized blocks that are sophisticated than Java's synchronized blocks. From Java 5 the package java.util.concurrent.locks contains several lock implementations.

The advantages of using locks are,

  • implements fairness.
  • possible to try to acquire the lock and backout immediately or after a timeout if the lock cannot be acquired.
  • possible to acquire and release locks in different scopes in any order.
