∧What does it mean in java?

The ^ operator in Java represents a bitwise XOR operation, and its rules are as follows: when both bits are 0, the result is 0, when both bits are 1, the result is 0, otherwise the result is 1. It is widely used to set or clear specific bits, swap two numbers, detect parity, and generate pseudo-random numbers.

In Java, the meaning of ^ operator

^# The ## symbol represents a bitwise XOR operation in Java. The rules for operating two binary bits are as follows:

If both bits are 0, the result is 0.
• If both bits are 1, the result is 0.
• If one of the two bits is 0 and the other is 1, the result is 1.

Example:

<code class="java">int num1 = 6; // 二进制表示为 110
int num2 = 5; // 二进制表示为 101

int result = num1 ^ num2; // 110 ^ 101 = 011 (3)</code>

Application of bitwise XOR operation:

Bitwise XOR operation is available Used to solve various problems, such as:

• Setting or clearing specific bits: Bitwise XORing a number with 1 can flip the value of the corresponding bit in the number.
• Exchange two numbers: You can use the bitwise XOR operation to exchange the values ​​​​of two numbers without using intermediate variables.
• Detect parity: When a number and its bitwise XOR result is 0, the number is even; otherwise, it is odd.
• Generate pseudo-random numbers: Bitwise XOR operation can be used to generate pseudo-random number sequences.
