public class Thread1 

{

public static void main(String[] arg)

{

Runnable r1 = new Runnable() 

{

 public void run() {

   try {

     while (true) {

       System.out.println("

Thread 1 run after 4 seconds

");

       Thread.sleep(4000);

     }

   } catch (InterruptedException iex) 

   {}

 }

};

Runnable r2 = new Runnable() 

{

 public void run() {

   try {

     while (true) {

       System.out.println("

Thread 2 run after 8 seconds

");

       Thread.sleep(8000);

     }

   } catch (InterruptedException iex) 

   {}

 }

};

Thread thr1 = new Thread(r1);

Thread thr2 = new Thread(r2);

thr1.start();

thr2.start();

}

}

Output:
