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 & (...
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 input bit--a one if the input bit is zero, a zero if the input bit is one. Bitwise operators can be combined with the = sign: &...

cat、 future、 generic、inner、 operator、 outer、rest、var、goto、byValue、cast、const 等都是Java尚未使用,但以后可能会作为关键字使用。 另外,Java 还有3个保留字:true、false、null。它们不是关键字,而是文字,包含 Java 定义的值。和关键字一样,它们也不可以作为标识符使用。
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...
Reduction is an operation already familiar to developers, though they might not recognize it at first: the COUNT() operator from SQL is one such operation (reducing from a collection of rows to a single integer), as are the SUM(), MAX(), and MIN() operators. Each of these takes a ...
If either of the arguments to a bitwise operator is a long, the result is a long. Otherwise, the result is an int. If the left operand of a shift operator is a long, the result is a long; otherwise, the result is an int.
