Which one is the best to create the Thread. i.e Implements Runnable or extends Thread.
I know that if we create thread by extending Thread class, multiple inheritance is not possible. So we can create thread by implementing Runnable to overcome this.
I want to Know if my class does not have super class , then which one is the best,Please justify.

First of all welcome to Ranch!!!
If you have to inherit a class already then I recommend "implements Runnable" because as you know a class cannot inherit multiple classes.
If you don't have to inherit any class then you can use either

No. *Always* implement Runnable. Your class is not a Thread, so it shouldn't extend it.
The mind is a strange and wonderful thing. I'm not sure that it will ever be able to figure itself out, everything else, maybe. From the atom to the universe, everything, except itself.
I agree. Here's the link:
