Program/Source Code:

The source code to create multiple threads is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to create multiple threads

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

    while (cnt < 5) {
      printf("Counter: %d\n", cnt);
      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()
  }
}

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

Explanation:

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

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.
