What bit operations are there in java and how to use them

1. XOR: ^

If one of the two input bits is 1 and the other is not 1, then the result after the "^" operation is 1

// 3: 0011
// 5: 0101
// ^的规则是:若两个输入位的某一个是 1，另一个不是 1，那么 "^" 运算后结果才是 1
// ---0110->6
System.out.println("3^5运算的结果是 :" + (3 ^ 5));

2, and:&

If both input bits are 1, the result after the "&" operation is 1, otherwise the result is 0

// 3: 0011
// 5: 0101
// &的规则是:若两个输入位都是 1，则"&" 运算后结果是 1，否则结果是 0
// ---0001->1
System.out.println("3&5运算的结果是 :" + (3 & 5));

or:|

If at least one of the two input bits is 1, then the result of the "|" operation is 1. If both are 0, the result is 0

// 3: 0011
// 5: 0101
// |的规则是:若两个输入位里至少有一个是 1，则"|" 运算后结果是 1，都是0的情况下结果是 0
// ---0111->7
System.out.println("3|5运算的结果是 :" + (3 | 5));

NOT:~

The logic of NOT is relatively simple, 0->1,1->0

//  3: 0011
// ~3: 1100-> -4
// 其中，第一位表示正负值
System.out.println("~3运算的结果是:" + ~3);
