Java Thread interrupted() method

The interrupted() method of thread class is used to check whether the current thread has been interrupted or not. This method clears the interrupted status of the thread that means if this method was to be called twice in succession, the second call would return false. If the interrupt status of a thread is true, this method will set the status to false.

Syntax

Return

This method will return true if the current thread has been interrupted otherwise returns false.

Example

public class JavaInterruptedExp extends Thread 
{ 
    public void run() 
    { 
        for(int i=1;i<=3;i++) 
        { 
            System.out.println("doing task....: "+i); 
        } 
    } 
    public static void main(String args[])throws InterruptedException 
    { 
        JavaInterruptedExp t1=new JavaInterruptedExp(); 
        JavaInterruptedExp t2=new JavaInterruptedExp(); 
        // call run() method 
        t1.start(); 
        t2.start();
        System.out.println("is thread t1 interrupted..: "+t1.interrupted());
        // interrupt thread t1 
        t1.interrupt(); 
        System.out.println("is thread t1 interrupted..: " +t1.interrupted()); 
        System.out.println("is thread t2 interrupted..: "+t2.interrupted()); 
    }
