My question is why it is needed to pass this keyword to the thread constructor eventhough we had created only one thread and if you say we have added to point to the current thread then why we have not added this in the following line "s=s1" Pls reply......

class MyThread extends Thread { Thread t; String s; MyThread(String s1) { s=s1; t=new Thread(this);//Point of concern t.start(); } public void run() { System.out.println(s); } }

public class ThreadDemo { public static void main(String [] args) { MyThread m=new MyThread("Thread Started...."); } }
