bitwise negation
You are assuming that 101 is three bits long. Java doesn't support variable length bit operations, it operates on a whole int of bits, so ~ will be ...,~uc is of type int (value 0xFFFF ). ucInverted is of type unsigned char (value 0xFF ), which is then promoted to int (value 0x00FF ). Thus they are not equal. ,The ~ (bitwise negation) operator yields the bitwise complement of the operand. In the binary representation of the result, every bit has the opposite value of the ... ,跳到 NOT - The bitwise NOT, or complement, is a unary operation that performs logical negation on each bit, forming the ones' complement of the given ... ,跳到 Bitwise NOT ~ / ones' complement (unary) - The ones' complement ( ~ ) or the bitwise complement gets us the complement of a given number. , Since int on your system is most likely a 32-bit number, all bits are flipped, including the ones that were insignificant zeros in the original ..., See two's complement for the representation of negative integers in many languages. As you can see, -2 is represented by 1111110 ; if you ..., Therefore right shift x by 31 and its negation by 31. One of those two will be a negative number and so right shifted by 31 will be 0xFFFFFFFF ...,接下來看看位元運算子（Bitwise operator），數位設計上有AND、OR、NOT、XOR 與補數等運算，在C 中提供這些運算的就是位元運算子，它們的對應分別是AND ...
