Bitwise Optimization in Java: Bitfields, Bitboards, and BeyondGlen Pepicelli
|= 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...
public static void main (String args[]) { byte x, y; x = 0x0F; y = 0x1F; int z; z = ((x & 0xFF) & ( y & 0xFF)) & 0xFF ; // Bitwise AND x and y System.out.println("z is " + z); // We expect output to be 0x0F or 15 in decimal } }Copyright...
Bitwise operators are most commonly used for testing and setting individual bits in a value. If either of the arguments to a bitwise operator is a long, the result is a long. Otherwise, the result is an int. Java's bitwise operators are ~ ("bitwise complement or not operator"), & ("...
Java provides an extensive bit manipulation operator for programmers who want to communicate directly with the hardware. These operators are used for testing, setting or shifting individual bits in a value. In order to work with these operators, one shou

以下是《Thinking in java》中的描述: The bitwise OR operator (|) produces a one in the output bit if either input bit is a one and produces a zero only if both input bits are zero. 如果输入(input)的两位中只要有一个为1,则或运算符会返回1。只有两个都是0,它才返回0。(假设输入(input)...

In Bitwise operations: Binary values are stored in two's complement. The tools work on 32-bit integers. The leftmost bit position is reserved for the sign of the value (positive or negative). If the integer is positive, the bit position is 0; if it's negative, the bit position is 1...
