I got it I was confused while reading javadocs..Please close it — Soul Enrapturer, Jan 01 '13 at 12:47

Just use .get():

return theSet.get(index);

It returns true if the bit is set and false otherwise.

+1 Technically, you don't need to know whether a 0 or 1 is used or something else. BitSet will tell you if the "bit" is *set or clear*. For example if you ask for a bit, beyond the size of the BitSet, e.g. `new BitSet(32).get(64)` will return false even though there is no 0 or 1 as such. – Peter Lawrey Jan 01 '13 at 12:50
