java 按位逻辑或 java按位与运算符,最近看JDK的源码,看到一些按位运算(BitwiseOperators),这里做个总结.1按位运算符汇总OperatorDescription&BitwiseAND(按位与)|BitwiseOR(按位或)^BitwiseXOR(eXclusiveOR,按位异或)~BitwiseComplement(按位取反)<<LeftShift(左

& the AND Operator (与运算符) 以下是《Thinking in java》中的描述: The bitwise AND operator (&) produces a one in the output bit if both input bits are one, otherwise it produces a zero. 如果输入(input)位都是1,则与运算符返回1。否则为0。(假设输入(input)是二个十进制数,则先取其二进...
The bitwise and shift operators are low-level operators that manipulate the individual bits that make up an integer value. The bitwise operators are most commonly used for testing and setting individual flag bits in a value. In order to understand their behavior, you must understand binary (base...
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 logical operators are AND(&), OR(|), XOR(^), and NOT(~). 3.1. Bitwise OR (|) The OR operator compares each binary digit of two integers and gives back 1 if either of them is 1. This is similar to the || logical operator used with booleans. When two booleans...
