Operators are symbols that perform operations in a program. For example, the + operator performs mathematical addition and string concatenation. Java provides various types of operators for mathematical operations, relational operations to check relationships between operands, logical operations to combine conditions, and bitwise operations to perform bit-level manipulations. Operators allow programmers to write code that manipulates data in meaningful ways.

2. An operator is a symbol which is used to perform
some operation in a program
For example + is a operator which is used to perform
mathematical addition and string concatination
operation

3. Java provides a rich set of operators they are divided
as follows

4. These operators are used to perform mathematical
operations.
Operator Description
+ Adds two operands
- Subtracts second operand from first
* Multiply two operands
/ Divide numerator by denumerator
% Gives remainder of division
++ Increments value by ONE
-- Decrements value by ONE

5. These operators are used check relation between the
two operands
Operator Description
<
>
<=
>=
==
!=

6. These operators are used to combine more than one
condition

operations
