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
• Bitwise Operators
• Logical Operators
• Assignment Operators
• Misc Operators

The Arithmetic Operators :

Operator	Description	Example
+	Addition - Adds values on either side of the operator	10 + 10 = 20
-	Subtraction - Subtracts right hand operand from left hand operand	20 - 10 = 10
*	Multiplication - Multiplies values on either side of the operator	2 * 2 = 4
/	Division - Divides left hand operand by right hand operand	10 / 2 = 5
%	Modulus - Divides left hand operand by right hand operand and returns remainder	10 % 2 = 0
++	Increment - Increases the value of operand by 1	1++ Given 2
--	Decrement - Decreases the value of operand by 1	2-- Given 1

The Relational Operators:

There are following relational operators supported by Java language

Operator	Description	Example
==	Checks if the values of two operands are equal or not, if yes then condition becomes true.	10 == 10 is true 10 == 20 is false
!=	Checks if the values of two operands are equal or not, if values are not equal then condition becomes true	10 != 10 is false 10 != 20 is true
>	Checks if the value of left operand is greater than the value of right operand, if yes then condition becomes true.	2 > 1 is true 4 > 2 is false
<	Checks if the value of left operand is less than the value of right operand, if yes then condition becomes true.	10 < 2 is false 2 < 10 is true
>=	Checks if the value of left operand is greater than or equal to the value of right operand, if yes then condition becomes true.	10>=10 is true
<=	Checks if the value of left operand is less than or equal to the value of right operand, if yes then condition becomes true.	10<=10 is true
