Operators in Java are symbols or special keywords used to perform various operations on variables, values, or expressions. Java supports a wide range of operators, which can be categorized into different types:

## Arithmetic Operators

**Addition (+**): Adds two operands.**Subtraction (-)**: Subtracts the second operand from the first operand.**Multiplication (*)**: Multiplies two operands.**Division (/)**: Divides the first operand by the second operand.**Modulus (%)**: Returns the remainder of the division of the first operand by the second operand.

## Assignment Operators

**Assignment (=)**: Assigns the value on the right to the variable on the left.**Compound Assignment Operators (e.g., +=, -=, *=, /=, %=)**: Combines an arithmetic operation with assignment.

## Increment and Decrement Operators

**Increment (++)**: Increases the value of a variable by 1.**Decrement (–)**: Decreases the value of a variable by 1.

## Relational Operators

**Equal to (==)**: Checks if two operands are equal.**Not equal to (!=)**: Checks if two operands are not equal.**Greater than (>)**: Checks if the left operand is greater than the right operand.**Less than (<)**: Checks if the left operand is less than the right operand.**Greater than or equal to (>=)**: Checks if the left operand is greater than or equal to the right operand.**Less than or equal to (<=)**: Checks if the left operand is less than or equal to the right operand.

## Logical Operators

**Logical AND (&&)**: Returns true if both operands are true.**Logical OR (||)**: Returns true if at least one of the operands is true.**Logical NOT (!)**: Reverses the logical state of the operand.

## Bitwise Operators

**Bitwise AND (&)**: Performs a bitwise AND operation between two operands.**Bitwise OR (|)**: Performs a bitwise OR operation between two operands.**Bitwise XOR (^)**: Performs a bitwise exclusive OR operation between two operands.**Bitwise NOT or Complement (~)**: Inverts the bits of the operand.**Left Shift (<<)**: Shifts the bits of the left operand to the left by a specified number of positions.**Right Shift (>>)**: Shifts the bits of the left operand to the right by a specified number of positions.**Unsigned Right Shift (>>>)**: Shifts the bits of the left operand to the right by a specified number of positions, filling the leftmost bits with zeros.

## Conditional (Ternary) Operator

**Ternary Operator (condition ? expr1 : expr2)**: Evaluates the condition and returns expr1 if true, otherwise returns expr2.

## Frequently Asked Questions

**What are operators in Java?**

Operators in Java are special symbols or keywords used to perform operations on variables and values, such as addition, subtraction, and comparison.

**How are operators classified in Java?**

Operators in Java are classified into categories, including arithmetic, assignment, relational, logical, bitwise, and conditional (ternary) operators.

**What is operator precedence in Java?**

Operator precedence determines the order in which operators are evaluated in an expression. Operators with higher precedence are evaluated first.

**What is the difference between the **`==`

operator and the `equals()`

method for comparing objects in Java?

`==`

operator and the `equals()`

method for comparing objects in Java?The `==`

operator compares object references, checking if two references point to the same object. The `equals()`

method is used to compare the contents or values of objects.

**What are the short-circuit logical operators (**`&&`

and `||`

) in Java?

`&&`

and `||`

) in Java?The short-circuit logical operators in Java (`&&`

and `||`

) evaluate only as many sub-expressions as necessary to determine the final result, potentially improving performance and avoiding unnecessary evaluation.
