Thread Interrupt In Java Example

Chapter: Thread Last Updated: 06-07-2016 11:20:20 UTC

Program:

            /* ............... START ............... */
                
public class JavaThreadInterrupt {
	public static void main(String[] args) {
		System.out.println("1:" + Thread.interrupted());
		// Now interrupt the main thread
		Thread.currentThread().interrupt();

		// Check if it has been interrupted
		System.out.println("2:" + Thread.interrupted());

		// Check again if it has been interrupted
		System.out.println("3:" + Thread.interrupted());
	}
}

                /* ............... END ............... */
        

Output

1:false
2:true
3:false

Notes:

• If any thread is in sleeping or waiting state if we call the interrupt() method on the thread it throws InterruptedException and breaks all Operations.
• A thread sends an interrupt by invoking interrupt on the Thread object for the thread to be interrupted.
• Three methods provided by the Thread class for interrupting a thread are below.
• 1. public void interrupt().
• 2. public static boolean interrupted().
• 3. public boolean isInterrupted().
