1) 有符号和无符号区别 java中只有 int型 而没有 unsigned integer 和 signed之分. Java 中一个有符号 int 类型的数是 32 位,他可以表示的范围是 -2^31 ~ 2^31-1 之间。那么如何表示负数?左边以 1 开始就是负的。 这就导致了移位操作符有“有符号”和“无符号”之分。这中区分仅存在于右移的时候。

CheckIn-Place Integer Swap with Bit Manipulation. right shift operator (>>):Moving all the bits of a number a specified number of places to the right. Note that a bitwise right-shift will be the equivalent of integer division by 2: 00000101(5) >> 1 --- 00000010(2) left shift operato...

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 ...
NO ONE wants to deal with libraries hiding the bit-manipulation if there is a naitive data type available, as this stands for LESS ERRORS. You mention a solution where assembler and some intrinsics are used … are you really serious ? What, if the code goes mobile, or to Spark processors...
