What does XOR mean in java?

XOR in Java is a binary-based bit operation, represented by the symbol "^". The operation rule is that for each binary bit of the numbers on both sides of the operator, the same value is 0, and the different value is 0 1. The XOR operation is most commonly used in polynomial division. The important property is reflexivity: "A^B^B=A", that is, for a given number A, use the same operation factor (B) to perform two XOR operations. Still get A itself.

Java is an object-oriented computer programming language. There are many kinds of operations in Java, including arithmetic operations, relational operations, bit operations, logical operations, assignment operations, etc. What I will tell you next is the XOR operation in bit operations.

XOR operation (^) in Java is an operation based on binary data.

That is to say, when the XOR operation is used in the code, the two conditions will be converted first and converted into binary data before the operation is performed. If the same bits in different fields have the same value (both are 0 or both are 1), they are 0, and if they are different (one is 0, the other is 1), they are 1.

^ If the corresponding bit values ​​are the same, the result is 0, otherwise it is 1

For example:

(A ^ B) Get 49, which is 0011 0001

Do you think it is very simple after understanding it? Try the Java code yourself to see if this is the case.
