Regarding Thread Creation

Question

Hello,
To create a thread in java there are two methods.
(1) by extending from thread class.
(2) by implementing runnable interface.
implementing runnable interface is the preferred method to create a thread because we still have the option to extend from any other class.
But does anybody know why java provides 2 methods for thread creation, why doesn't it provide only option 2 (i.e. by implementing runnable interface) when it is the preferred option.
Regards,
Sandy.

Answer 1

Though Runnable interface is preferred to create threads in Java,most programmers extends Thread class.As jschell would say, 'I am rather certain' that the opposite is true.
The reason behind of this is that you can have a clear logic of your code by using ThreadThat's not even true and it certainly isn't a reason to extend Thread rather than implement Runnable.
most of the system programming written in java used Thread class instead of Runnable interface .If you have some evidence on the point please produce it. The consensus of opinion on these forums has been the other way round for many years.
