![]() ![]() The synchronized keyword can be used with: It also protects shared resources within the block. This synchronized keyword helps in writing concurrent parts of any application. A critical section is where only one thread is executing at a time, and the thread holds the lock for the synchronized section. Javasynchronized keyword marks a block or a method a critical section. Thread T1 = new Thread( "Thread - 2 ", MT) Thread T = new Thread( "Thread - 1 ", MT) Every time we run it, it produces the same result. This is the same example as above but it prints the counter value in the sequence. Thread t1 = new Thread( "Thread - 2 ", MT) Thread t = new Thread( "Thread - 1 ", MT) T = new Thread (this, threadName) t.start () Here is a simple example which prints the counter value in a sequence and every time we run it, it produces a different result based on CPU availability to a thread. The lock() method locks the Lock instance so that all threads calling lock() are blocked until unlock() is executed. Public synchronized void lock() throws InterruptedException This is how a lock looks like: public class Lock ![]() So a thread that needs consistent access to an object’s fields needs to acquire the object’s lock before accessing them, and then release the lock when the work is done.įrom Java 5, the package contains many lock implementations. Each and every object has a lock associated with it. ![]() Locks in JavaĪs I mentioned earlier, Synchronization is built around an internal entity known as the lock or monitor. Let’s not get into the details of these types and try to understand what are locks in Java.
