Program/Source Code:

The source code to sleep a thread is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to sleep a thread

class MyThread extends Runnable {
  override def run() {
    var cnt: Int = 0;

    while (cnt < 5) {
      printf("Counter: %d\n", cnt);
      Thread.sleep(500);
      cnt = cnt + 1;
    }
  }
}

object Sample {
  // Main method
  def main(args: Array[String]) {
    var ex = new MyThread();
    var thrd1 = new Thread(ex);
    var thrd2 = new Thread(ex);

    thrd1.start()
    thrd2.start()
  }
}

Output:

Counter: 0
Counter: 0
Counter: 1
Counter: 1
Counter: 2
Counter: 2
Counter: 3
Counter: 3
Counter: 4
Counter: 4

Explanation:

Here, we created a class MyThread by implementing the Runnable interface and the implement run() method.

We created a class MyThread by implementing the Runnable interface and implement the run() method. In this method, we used the Thread.sleep() method to sleep a thread for a specific time.

In the main() function, we created an object of the MyThread class and bind with Thread class objects, and called the start() method to run the created threads.
