Operators are special symbols that perform specific operations on one, two, or
three operands, and then return a result.
The operators in the following table are listed
according to precedence order. The closer to the top of the table an operator
appears, the higher its precedence. Operators with higher precedence are
evaluated before operators with relatively lower precedence. Operators on the
same line have equal precedence. When operators of equal precedence appear in
the same expression, a rule must govern which is evaluated first. All binary
operators except for the assignment operators are evaluated from left to right;
assignment operators are evaluated right to left.
In general-purpose programming, certain operators tend to
appear more frequently than others; for example, the assignment operator
"=" is far more common than the unsigned right shift operator
">>>". With that in mind, the following discussion focuses
first on the operators that you're most likely to use on a regular basis, and
ends focusing on those that are less common. Each discussion is accompanied by
sample code that you can compile and run. Studying its output will help
reinforce what you've just learned.
