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.

Answer 1

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

Answer 2

尝试java.util.BitSet或java.math.BigInteger 。
