Bitwise operation on byte type */ class bitwise{ public static void main (String args[]) { byte x, y; x = 0x0F; y = 0x1F; byte z; z = x & y; // Bitwise AND x and y System.out.println("z is " + z); // We expect output to be 0x0F or 15 in decimal } }Howe...
操作System.out.println((longValue >> n & 1) == 1); 可以判断值longValue的2进制表示中,从右边数到左边第n + 1位的值是0false 还是1true publicclass bitOperation { /** * @param args */ publicstaticvoid main(String[] args) { long longValue =0; longValue = longValue | (1 <<0); ...
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...
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...
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)...
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。
|= 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...
35 = 00100011 (In Binary) Bitwise complement Operation of 35 ~ 00100011 ___ 11011100 = 220 (In decimal) Twist in Bitwise Complement Operator in C Programming The bitwise complement of 35 (~35) is -36 instead of 220, but why? For any integer n, bitwise complement of n will be -(n ...
