Program/Source Code:

The source code to set and get the priority of the thread is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to set and get the
// priority of thread

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

    while (cnt < 5) {
      println(this.getName() + "->" + this.getPriority());
      cnt = cnt + 1;
    }
  }
}

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

    thrd1.setName("Thread1")
    thrd2.setName("Thread2")

    thrd1.setPriority(Thread.MIN_PRIORITY)
    thrd2.setPriority(Thread.MAX_PRIORITY)

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

Output:

Thread1->1
Thread1->1
Thread1->1
Thread1->1
Thread1->1
Thread2->10
Thread2->10
Thread2->10
Thread2->10
Thread2->10

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, 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 two objects of the MyThread class and set the name and priority of threads using setName() and setPriority() methods, and print the name of thread and priority in the run() method using getName() and getPriority() methods on the console screen.
