Using arithmetic operators should include outlining the available operators in Java and their possible uses:

Operator

Use

Description

+

op1 + op2

Adds op1 and op2

-

op1 - op2

Subtracts op2 from op1

*

op1 * op2

Multiplies op1 by op2

/

op1 / op2

Divides op1 by op2

%

op1 % op2

Computes the remainder of dividing op1 by op2


These short-cut operators increment or decrement a number by one:

Operator

Use

Description

++

op++

Increments op by 1; evaluates to the value of op before it was incremented

++

++op

Increments op by 1; evaluates to the value of op after it was incremented

--

op--

Decrements op by 1; evaluates to the value of op before it was decremented

--

--op

Decrements op by 1; evaluates to the value of op after it was decremented


These are the Java programming language's other arithmetic operators:

Operator

Use

Description

+

+op

Promotes op to int if it is a byte, short, or char

-

-op

Arithmetically negates op
