Java Bitwise Operators Java中的位操作指定包括: ~按位非(NOT) &按位与(AND) |按位或(OR) ^按位异或(XOR) >>右移 >>>无符号右移 <<左移 前面几个都非常简单,主要是移位操作比较容易出错. 首先要搞清楚参与运算的数的位数,如int的是32位。long的是64位。 如int i = 1; i的二进制原码表示为: ...
不借助与第三个变量,实现两个数的交换10intx = 10;11inty = 20;1213//方案一:14x = x + y;//x = 3015y = x - y;//y = 1016x = x - y;//x = 2017
Also, logical operators always evaluate the first boolean expression and, depending on its result and the operator used, may or may not evaluate the second. On the other hand, bitwise operators always evaluate both operands. Finally, logical operators are used in making decisions based on multi...
~ the NOT Operator(非运算符) 以下是《Thinking in java》中的描述: The bitwise NOT (~, also called the ones complement operator) is a unary operator; it takes only one argument. (All other bitwise operators are binary operators.) 非运算符是一个一元运算符,它只需要一个参数。(其它的位运算符...

The Java programming language also provides operators that perform bitwise and bit shift operations on integral types. The operators discussed in this section are less commonly used. Therefore, their coverage is brief; the intent is to simply make you aware that these operators exist. The unary ...
4.4 Bitwise and Shift Operators 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, ...

In C++, bitwise operators perform operations on integer data at the individual bit-level. These operations include testing, setting, or shifting the actual bits. For example, a & b; a | b; Here is a list of 6 bitwise operators included in C++. OperatorDescription & Bitwise AND Operator |...
