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.
