按位“非”(~ ,也称为取补运 算,ones compliement operator )属于一元操作符;它只对一个操作数进行操作(其他位操 作是二元运算)。按位“非”生成与输入位相反的值——若输入 0,则输出 1;输入 1,则输 出 0。 位操作符和逻辑操作符都使用了同样的符号。因此,我们能方便地记住它们的含义:由于“位” ...

The following program, BitDemo, uses the bitwise AND operator to print the number "2" to standard output. class BitDemo { public static void main(String[] args) { int bitmask = 0x000F; int val = 0x2222; // prints "2" System.out.println(val & bitmask); } } «...
The bitwise Or operator (|) produces a one in the output bit if either input bit is a one and product a zero only if both input bits are zero. The bitwise EXCLUSIVE OR or XOR (^), produces a one in the output bit if one or the other input bit is a one, but not both. The ...

symbol . it’s a bitwise operator , meaning it’s an operator comparing the matching bits of two values in order to return a result. in the xor case, if two bits of the same position have the same value, the resulting bit will be 0. otherwise, it’ll be 1. so instead of our ...
