Numeric Operators

In the last section, we created and initialized some variables. Now let's look at Java's facilities for numeric operations. They will look very familiar to C programmers, but there are some differences. Operators that perform arithmetic or numeric comparison are shown in Table 3.2. The precedence gives the order in which the compiler performs operations, with 1 being the first. You can always use parentheses to control the order in which operations are performed.

Table 3.2. Numeric Operators in Java

Precedence	Operator	Description
1	++	Increment by 1 (or 1.0)
1	--	Decrement by 1 (or 1.0)
1	+	Unary plus
1	-	Unary minus
2	*	Multiplication
2	/	Division
2	%	Modulo
3	+	Addition
3	-	Subtraction
5	<	Less than test
5	>	Greater than test
5	<=	Less than/equal test
5	>=	Greater ...
