Binary OperatorsBecause data in the computer is in binary format, Java provides binary operators for direct operations. This is the bitwise operators and shift operators to be explained below.Binary operators can be used to operate numbers directly
The operator that can operate only one value is called The unary operator. The unary operator includes the increment (decrement) operator and the

Bitwise operations are used and when bit resetting is used, when a location can be used or if reverse and exchange are to be obtained, it is easy to use an exclusive or shift operation. Point 1: they are binary operators, and the two computation
shift operatorThe shift operator is the translation of numbers on the basis of binary. According to the direction of the translation and the rules of padding numbers are divided into three kinds of:> (with symbol right move) and >>> (unsigned Right
