Web0. If all you want is the least significant byte of an integer (as your question is stated), then it's very simple: byte b = (byte) (x & 0xFF); This works because all the high bits of 0xFF will be set to 0 by default, so you are masking out everything but the bottom byte. A byte is 8 bits and each 'F' is 4 bits (written in hexadecimal). WebMay 20, 2011 · 2 Answers. n & ~1 replaces the least significant bit of n with zero; n 1, with one. To replace the LSB with b, where b can be either 0 or 1, you can use (n & ~1) b. To replace the k -th bit with b (where k=0 stands for the LSB): (n & ~ (1 << k)) (b << k). I have always to check before if my replacing bit is 0 or 1.
