Scala - Implementing a Thread by Extending Thread Class

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

Scala code to create a thread by extending Thread class

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.
