Java example to interrupt the execution of a thread.
Submitted by Nidhi, on April 10, 2022

Problem statement

In this program, we will create a thread and interrupt the thread execution using the interrupt() method.

Source Code

The source code to interrupt the execution of a thread is given below. The given program is compiled and executed successfully.

// Java program to interrupt the execution 
// of a thread

class MyThread implements Runnable {
  public void run() {
    try {
      Thread.sleep(1000);
      System.out.println("Includehelp");
    } catch (Exception e) {
      System.out.println("Exception: " + e);
    }
    System.out.println("Thread is running");
  }
}

public class Main {
  public static void main(String[] args) {
    try {
      Thread t = new Thread(new MyThread());

      t.start();

      t.interrupt();

    } catch (Exception e) {

    }
  }
}

Output

Exception: java.lang.InterruptedException: sleep interrupted
Thread is running

Explanation

In the above program, we created two classes MyThread and Main. We created MyThread class by implementing the Runnable interface. In the run() method, we handled exceptions using try, catch blocks.

The Main class contains a main() method. The main() method is the entry point for the program. Here, we created a thread. Then we started and interrupted the thread using the start(), interrupt() methods respectively.
