& In Java | and ^ arithmetic

If the two input bits are all 1, the bitwise AND operator (&) generates an output bit of 1, otherwise an output bit 0 is generated. If one of the two input bits is 1, the bitwise OR operator (|) generates an output bit 1, and only if two input bits are 0. It generates an output bit 0. If one of the input bits is 1, but not all 1, then the bitwise XOR operator (^) generates an output bit of 1. Bitwise "NOT" (~), also known as the inverse operator, is a hospital operator that operates on only one operand
