Bitwise operations in Java
Java bit operator
Bitwise operators are used to operate binary bits. Java provides bitwise operators as shown below:
Bitwise operator (>>,>>,&, |, ^ ,~ ), In the bitwise operator, ~ The others are binary operators. The
We've explained PHP arithmetic operators, PHP string operators, assignment operators, and today we'll give you a detailed introduction to the PHP operator

Bit operators are not often used in PHP, but they are still very useful,

In-depth understanding of bitwise XOR Operators
The two values involved in the operation. If the two bits are the same, the result is 0. Otherwise, the result is 1.That is:0 ^ 0 = 0,1 ^ 0 = 1,0 ^ 1 = 1,1 ^ 1 = 0Three Characteristics of bitwise XOR:(
Comparison between bitwise operation and multiplication and division operation.
Many bitwise operations exist in Java JDK. The purpose is to make the code run faster. Let's conduct an experiment to see how much computing time can be saved.
