Define Thread by extending Thread class

class myThread  extends Thread

{

    public void run()

    {

        for(int i=1; i<=10; i++)

        {

            System.out.println("Child thread is running ");

        }

    }

}

class ThreadExtend

{

    public static void main(String args[]) throws InterruptedException

    {

        myThread t = new myThread();

        t.start();

        for(int i=1; i<=10;i++)

        {

            System.out.println("Main thread ");
