Scala - Multi-Tasking Using Thread

Here, we will implement multitasking by creating a class extended by Thread class. And, we will override the run() method and also defined one more method to demonstrate multi-tasking using thread.

Scala code to implement multi-tasking using thread

The source code to implement multi-tasking using thread is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to implement multi-tasking
// using thread

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

    while (cnt < 5) {
      println("###cnt: " + cnt);
      Thread.sleep(100);
      cnt = cnt + 1;
    }
  }

  def myTask() {
    var cnt: Int = 0;

    while (cnt < 5) {
      println("@@@cnt: " + cnt);
      cnt = cnt + 1;
      Thread.sleep(200);
    }
  }
}

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

    thrd.start();
    thrd.myTask();
  }
}

Output

@@@cnt: 0
###cnt: 0
###cnt: 1
@@@cnt: 1
###cnt: 2
###cnt: 3
@@@cnt: 2
###cnt: 4
@@@cnt: 3
@@@cnt: 4

Explanation

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

Here, we created a class MyThread by extending the thread class and implement the run() method and also defined one more method myTask() to demonstrate multi-tasking using thread.

And, we also created a singleton object Sample and defined the main() function. The main() function is the entry point for the program.

In the main() function, we created an object of the MyThread class and start thread execution, and also call myTask() method.
