Java provides operators to manipulate variables including arithmetic operators for mathematical expressions like algebra, relational operators to test relations between entities and typically evaluate to true or false, and assignment operators to set values.

1. Java provides a rich set of operators to manipulate variables.
We will discuss commonly used operators.

2. The Arithmetic Operators:
Arithmetic operators are used in mathematical expressions in the same
way that they are used in algebra.

4. The Relational Operators:
operator that tests or defines some kind of relation between two entities.
these operators usually evaluate to true or false.

8. The Assignment Operators
