Java program to sleep a thread

Java example to sleep a thread.
Submitted by Nidhi, on April 08, 2022

Problem statement

In this program, we will create a thread with the runnable interface. Then we will create multiple threads and a sleep thread execution Thread.Sleep() method.

Source Code

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

// Java program to sleep a thread

class MyThread implements Runnable {
  public void run() {
    int i = 0;

    try {
      for (i = 1; i <= 3; i++) {
        System.out.println("Thread " + Thread.currentThread().getId() + " is running");

        Thread.sleep(1000);
      }
    } 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();
    t3.start();
  }
}

Output

Thread 11 is running
Thread 12 is running
Thread 10 is running
Thread 11 is running
Thread 12 is running
Thread 10 is running
Thread 11 is running
Thread 12 is running
Thread 10 is running

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 the three threads and executed them. In the run() method, we used Thread.Sleep() method to sleep thread execution for a specific time.
