~ 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...
Bitwise and Bit Shift OperatorsThe 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...
Java Bit Shift Operators In addition to above bitwise operators, Java provides three flavors of bitwise shift operators that are left shift (<<), right shift (>>) and zero-fill right shift (>>>). The notable difference between right shift and zero-fill right shift is that in right shift...

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。
Java bitwise operators can be applied to the integer types:long, int, short, char, byte. Bitwise Operators act upon the individual bits of their operands. Left Shift It has this general form: value << num The following code shifts byte type variable. ...
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
