Hi all

When do we create a thread instance using a thread class and when do we implement the Runnable interface? Which one is preferred and why?

Both are the ways of creating a thread in java, but we prefer Interfaces over inheritance because it gives you flexibility to extend other class you might want.

I will extend Thread class only when my class has to be a thread only.(IS-A).

My class has to do other things beside being a thread like calculations, calling other interfaces, joining results then i will better choose Interface.Hope that will help you.
