source code to demonstrate thread sleep method

package thread;

class MyTh extends Thread
    {
    public void run()
    {
    for(int i=0;i<3;i++)
    {
    System.out.println("child thread");
    try
    {
    Thread.sleep(1000);
    }
    catch(InterruptedException e){}
    }
    }
    
    }
public    class ThreadDemo2
    {
    public static void main(String a[])throws Exception
    {
        MyTh t=new MyTh();
        t.start();
        for(int i=0;i<2;i++){
        System.out.println("main thread");
        }
    }
    }

output:
mainthread
child thread
mainthread

child thread
