# JAVA #06 – Operators in Java

Java provides a rich set of operators to manipulate variables. We can divide all the Java operators into the following groups:

• Arithmetic Operators
• Relational Operators
• Logical Operators
• Assignment Operators
• Increment/Decrement Operators • The Arithmetic Operators:

Arithmetic operators are used in mathematical expressions in the same way that they are used in algebra. The following table lists the arithmetic operators:

Assume integer variable A holds 10 and variable B holds 20, then:

 SR.NO Operator and Example 1 + ( Addition ) Adds values on either side of the operator Example: A + B will give 30 2 – ( Subtraction ) Subtracts right hand operand from left hand operand Example: A – B will give -10 3 * ( Multiplication ) Multiplies values on either side of the operator Example: A * B will give 200 4 / (Division) Divides left hand operand by right hand operand Example: B / A will give 2 5 % (Modulus) Divides left hand operand by right hand operand and returns remainder Example: B % A will give 0 6 ++ (Increment) Increases the value of operand by 1 Example: B++ gives 21 7 — ( Decrement ) Decreases the value of operand by 1 Example: B– gives 19
