I\'m trying to set bits in Java byte variable. It does provide propper methods like .setBit(i). Does anybody know how I can realize this?
I. Just implemented a kind of bitwise trie (based on nedtries), but my code does lot Of memory allocation (for each node).
I am looking at the following SHA256 pseudocode on wikipedia. Specifically, I am looking at the following section.
I have a 32-bit integer value and I want to translate that into two decimal values. One value from the 5 least sign开发者_Python百科ificant bits and one decimal value from the rest of the bits (27 bit

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