This operator combines its two integer operands by performing a Boolean XOR (Exclusive OR) operation on their individual bits. The result has a bit set if the corresponding bits in the two operands are different. If the corresponding operand bits are both ones or both zeros, the result bit i...

The bitwise ^ operator performs a bitwise exclusive OR operation. The bitwise | operator performs a bitwise inclusive OR operation. 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)...
NOT: Bitwise NOT(~), or the compliment operator, is aunary operationthat performs a logical negation on each individual bit in a bit pattern, so, 0’s become 1’s and vise-versa. This operator will convert the number into a signed 32-bit integer and then performs a bitwiseOne’s Compl...
|= performs an in-place operation (原地运算符) between pairs of objects. In particular, between: sets: a union operation dicts: an update operation counters: a union (of multisets) operation numbers: a bitwise OR, binary operation In most cases, it is related to the | operator. See examp...
The output of bitwise AND is 1 if the corresponding bits of two operands is 1. If either bit of an operand is 0, the result of corresponding bit is evaluated to 0. In C Programming, the bitwise AND operator is denoted by &. Let us suppose the bitwise AND operation of two integers ...
Let’s see the binary representation of this operation: 0110 0101 --- 0111 Here, we can see that using OR, 0 and 0 will result in 0, while any combination with at least a 1 will result in 1. 3.2. Bitwise AND (&) The AND operator compares each binary digit of two integers and...
原来Java内部在做移位(shift operation)操作时,会将右边的shift distance和0x3f按位与后,在做移位操作,这样就能保证移位的范围总是0~63。也就是说对于long类型的位移操作Java内部自动给我们做了% 64的处理。类似的,如果是int类型的操作,Java内部会将移位的距离& 0x1f确保移位范围在0~31。
