按位“非”(~ ,也称为取补运 算,ones compliement operator )属于一元操作符;它只对一个操作数进行操作(其他位操 作是二元运算)。按位“非”生成与输入位相反的值——若输入 0,则输出 1;输入 1,则输 出 0。 位操作符和逻辑操作符都使用了同样的符号。因此,我们能方便地记住它们的含义:由于“位” ...
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 EXCLUSIVE OR or XOR (^), produces a one in the output bit if one or the other input bit is a one, but not both. The bitwise NOT (~, also called the ones complement operator) is a unary operator; it takes only one argument. Bitwise NOT produces the opposite of the inp...

operator, like the other bitwise operators, works with every primitive type. for example, let’s consider two integers, 1 and 3, whose binary representations are 00000001 and 000000011, respectively. using the xor operator between them will result in the integer 2: assertthat(1 ^ 3).isequal...

are overloaded for logical and bitwise operations. Let's see how we can achieve polymorphism using operator overloading. The + operator is used to add two entities. However, in Java, the + operator performs two operations. 1. When + is used with numbers (integers and floating-point numbers...
INT10-C Do not assume a positive remainder when using the % operator. INT12-C Do not make assumptions about the type of a plain int bit-field when used in an expression. INT13-C Use bitwise operators only on unsigned operands. INT14-C Avoid performing bitwise and arithmetic opera...
