Submitted by Nidhi, on April 09, 2022

Problem statement

In this program, we will create a thread with the runnable interface. Then we will create multiple threads. Here we will suspend and stop a thread using the suspend(), stop() methods respectively.

Source Code

The source code to stop a thread is given below. The given program is compiled and executed successfully.

// Java program to stop a thread

class MyThread implements Runnable {
  public void run() {
    try {
      Thread.sleep(500);
      System.out.println(Thread.currentThread().getName());
    } catch (Exception e) {

    }
  }
}

public class Main {
  public static void main(String[] args) {
    Thread t1 = new Thread(new MyThread());
    Thread t2 = new Thread(new MyThread());
    Thread t3 = new Thread(new MyThread());

    t1.start();
    t2.start();
    t2.suspend();
    t3.start();
    t2.resume();
  }
}

Output

Thread-0
Thread-2

Explanation

In the above program, we created two classes MyThread and Main. We created MyThread class by implementing the Runnable interface.

The Main class contains a main() method. The main() method is the entry point for the program. Here, we created three threads and started all threads one by one. Here, we suspended and stopped t2 thread using suspend(), stop() methods.
