Practical 17

Aim:- Write a program to show usage of isAlive() and join() method.

JAVA Code :-

import java.lang.*;

class NewThread extends Thread

{

  String str;

  NewThread(String name) {

    super(name);

    str=name;

    System.out.println(name +this);

    start();

  }

  public void run() {

    try {

       for(int i=5;i>0;i--)

       {

              System.out.println(str +": " +i);

              sleep(1000);

        }

    }

    catch(InterruptedException e) {

            System.out.println("Chlid interrupted ");

    }

    System.out.println("Exiting " +str +" thread ");

  }

}

class Testjoin

{

  public static void main(String args[])

  {

     NewThread one=new NewThread("One");

     NewThread two=new NewThread("Two");

     System.out.println("One Thread is alive: " +one.isAlive());

     System.out.println("Two Thread is alive: " +two.isAlive());

     try {

         one.join();

         two.join();

      }

      catch(InterruptedException e) {

            System.out.println("Interrupted found");

      }

     System.out.println("One Thread is alive: " +one.isAlive());

     System.out.println("Two Thread is alive: " +two.isAlive());

     System.out.println(" Main thraed exiting");

  }

}

Output:-
