I have one doubt about Thread (I have face this question in an interview and searching for answer):-
to get Thread instance we have options
1. extend Thread class
2.after implementing Runnable interface
question is why do we need Thread class even we can get same things after implementing runnable interface directly ?
I have given answer in interview,
that Thread class implement runnable interface so we no need to implement methods again but interviewer was not satisfied with this answer.
and other answer which we always give for this question :
we can extend any other class when we use runnable interface.
please give your view.

The Thread class creates the new thread and then runs your Runnable class in it. If you didn't have the Thread class all your classes that implement Runnable would also have to include code to create and manage a thread.
