ava provides a rich operator environment. Most of its operators can be divided into the
following four groups: arithmetic, bitwise, relational, and logical. Java also defines some
additional operators that handle certain special situations. This chapter describes all
of Java's operators except for the type comparison operator instanceof, which is examined
in Chapter 13.
Arithmetic operators are used in mathematical expressions in the same way that they are
used in algebra. The following table lists the arithmetic operators:
Subtraction (also unar y minus)
The operands of the arithmetic operators must be of a numeric type. You cannot use
them on boolean types, but you can use them on char types, since the char type in Java is,
essentially, a subset of int.
