从上面的代码输出中,我们会发现对应的 2 进制长度不一样,因为在 Java 程序中对于二进制,前面为 0 的时候,在输出的时候会进行丢弃的。 所以显示的长度不一样,如果希望显示长度一致的话,前面补 0 就可以了。 https://www.ossez.com/t/java-shift-operator/14594...
Java 中的移位运算符主要包括以下三种:左移运算符:将数值转换为二进制后,向左移动指定位数。低位补零。例如,数值 5左移 1 位后变为 10。带符号右移运算符:将数值转换为二进制后,向右移动指定位数。高位根据数值的符号位补零或补一。例如,数值 5带符号右移 1 位后变为 2;数值 5带符号右...
移位操作符(shift operator) 移位操作符操作的运算对象也是二进制的“位”,但是它们只可以被用来处理整数类型(基本类型的一种)。左移位操作符(<<)能将操作符左边的运算对象向左移动操作符右侧指定的位数(在低位补0)。“有符号”右移位操作符(>>)则将操作符左边的运算对象向右移动操作符右侧指定的位数。“有符号...

Bit operator: Left shift and Right shift (Signed or unsigned? ) No matter left shift or right shift, the result's sign should always be the same as its left operand. By default, const numbers in C/C++ is signed. -W c++ 数据 转载 mob604757008d56 2017-04-16 10:24:00 234阅读 ...
Ternary Operator Java includes a special ternary (three-way) operator that can replace certain types of if-then-else statement. Java包含一个特殊的运算符(三元运算符),可以替代语句if-then-else类型。 expression1 ? expression2 : expression3
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 bitwise complement operator "~" inverts a bit pattern; it can be applied to any of the integral types, making ...
