how to override thread.start() method in java?

Question

I need to implement thread.start() method in my java code. Please let me know through an example of overriding of thread.start() method and how it works?

Answer 1

Actually, you can call run() to run a thread instead of start() to run a thread. But there is a little difference.

Suppose you create two threads:

Thread t1 = new Thread();
Thread t2 = new Thread();

Case 1 : If you call "t1.run()" and "t2.run()" one after another they will start to run t1 and t2 synchronously (sequentially).

Case 2 : If you call "t1.start()" and "t2.start()" one after another they will call their run() methods and start to run t1 and t2 asynchronously (in parallel).
