左移运算符(left shift operator):<< 规则 左移几位,就在最低位补几个0 示例 3<<2 3乘2的2次方法 = 12 0000001100 3<< 3 3乘2的3次方法 = 24 00000011000 结论 左移几位,就是该数乘以2的几次方法 右移运算符(right shift operator):>> 规则 对于高位出现的空位,原来高位是什么,就拿什么来补 ...
在JLS(Java Language Specific 15.19)中有例如以下解释: If the promoted type of the left-hand operand is int, only the five lowest-order bits of the right-hand operand are used as the shift distance. It is as if the right-hand operand were subjected to a bitwise logical AND operator & (...
无符号右移,忽略符号位,空位都以0补齐 value >>> num -- num 指定要移位值value 移动的位数。 无符号右移的规则只记住一点:忽略了符号位扩展,0补最高位 无符号右移运算符>>> 只是对32位和64位的值有意义 E | hongtenzone@foxmail.com B |http://www.cnblogs.com/hongten...
and the signed right shift operator ">>" shifts a bit pattern to the right. The bit pattern is given by the left-hand operand, and the number of positions to shift by the right-hand operand. The unsigned right shift operator ">>>" shifts a zero into the leftmost position, while the...
