bitwise operation class in Java

Question

is there a class that makes bitwise operation easier ? I need some methods that reads into integer the "value" of bits givem their offset and length (in a 32/64 bits byte array).

I can use the bit manipulations available with java but I rather use a debugged class.

What do you mean a debugged class? If the bitwise operators didn't work, the Java Language would be broken. — Amir Afghani

I think "debugged" means "part of the standard library." E.g. tested, working, reliable. — Paul Sasik

Take a look at BitSet. And here is a usage example that looks like it demonstrates code similar to what you need to do.

Try java.util.BitSet or java.math.BigInteger.
