How to operate XOR in Java?

The XOR operation in Java is 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 then converted into binary data. Operation. Operation rules: In the same bit of the two operands, if the values ​​​​are the same (both 0 or both 1), it is 0, and if they are different (one is 0, the other is 1), it is 1.

The bitwise operators in Java are mainly for binary, which include: "AND", "NOT", "OR", "XOR". On the surface, it seems a bit like logical operators, but logical operators perform logical operations on two relational operators, while bit operators mainly perform logical operations on the bits of two binary numbers.

The following is an introduction to the use of the XOR operator:

XOR operator

The XOR operation (^) is based on binary data. Basic calculations. 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.

The operation rule is: if the bits of the two operands are the same, the result is 0, and if they are different, the result is 1.

Let’s look at a simple example.

public class data16
{
public static void main(String[] args)
{
int a=15;
int b=2;
System.out.println("a 与 b 异或的结果是："+(a^b));
}
}

Running result

The result of XOR between a and b is:

13

Analyze the above program segment: the value of a is 15, conversion It is 1111 in binary system, and the value of b is 2, and it is 0010 in binary system. According to the operation rules of XOR, it can be concluded that the result is 1101 or 13.
