i + OPERATORS
An operator is a symbol that tells the compiler to perform specific mathematical or logical
calculations. It requires operands or values to perform calculations and returns the desired result.
For example:
int x = y + z;
or
int x = 10 + 20;
In the above example, the plus (+) operator is used to calculate the sum of two variables (y and z)
or values (10 and 20). It calculates the sum and assigns the result to the variable x.
There are various types of operators in Java, which are as follows:
• Arithmetic operators
• Relational operators
• Logical operators
• Unary operators
• Assignment operators
Let's discuss these in detail.
Arithmetic Operators
Arithmetic operators are used to do basic mathematical calculations. They consist of both unary
operators, which operate on a single operand, and binary operators, which require two operands.
These are as follows:
Example
Operator Description Syntax Output
(int a = 11, b = 4)
+ Returns the result after performing the a + b a + b 15
addition addition operation.
– Returns the result after performing the a – b a – b 7
subtraction subtraction operation.
* Returns the result after performing the a * b a * b 44
multiplication multiplication operation.
/ Returns the result after performing the a / b a / b 2
division division operation.
% Returns the remainder after performing a % b a % b 3
modulus the division operation.
Relational Operators
Relational operators help to compare quantities and return the Boolean value ‘True’ or ‘False’ as
a result. These are also known as comparison operators.
Example
Operator Description Syntax Output
(int a = 11, b = 4)
== This operator is used to check the (a == b) a == b false
Equal to equality between two values. a == 11 true
