Scala program to create a thread by extending Thread class

Here, we are going to learn how to create a thread by extending Thread class in Scala programming language?
Submitted by Nidhi, on July 17, 2021

Problem Solution:

Here, we will create a thread by extending the Thread class and start created thread using the start() method.

Program/Source Code:

The source code to create a thread by extending the Thread class is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to create a thread 
// by extending Thread class

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

    while (cnt < 5) {
      println("Thread is running...");
      cnt = cnt + 1;
    }
  }
}

object Sample {
  // Main method
  def main(args: Array[String]) {
    var thrd = new MyThread()
    thrd.start()
  }
}

Output:

Thread is running...
Thread is running...
Thread is running...
Thread is running...
Thread is running...

Explanation:

Here, we used an object-oriented approach to create the program. And, we created an object Sample.

We created a class MyThread by extending the Thread class and implement the run() method.

In the main() function, we created an object of the MyThread class and run the thread by calling the start() method.
