I have a set ={1,2,3,4}. I want to create power set of this set. One way to create the power set is to take every element as binary(0/1) and print all possible combination.
I was thinking about some utility/library in java to do the same.

You did not mention your use case but unless your sets are really small this is probably not what you want. Consider other ways to solve the underlying problem. – Henry Sep 16 '14 at 05:41
