Operators in Java Explained: Arithmetic, Relational, and Logical

Operators in Java

Operators are special symbols used to perform operations on variables and values in Java. Java provides several types of operators to perform arithmetic, logical, relational, and other operations.

1. Arithmetic Operators

     Used to perform basic mathematical operations.

• + Addition
• - Subtraction
• * Multiplication
• / Division
• % Modulus (remainder)

2. Relational Operators

     Used to compare two values and return a boolean result (true or false).

• > Greater than
• < Less than
• >= Greater than or equal to
• <= Less than or equal to
• == Equal to
• != Not equal to

3. Compound Assignment Operators

     Used to perform an operation and assign the result to the same variable.

• += Add and assign
• -= Subtract and assign
• *= Multiply and assign
• /= Divide and assign
• %= Modulus and assign

4. Unary Operators

     Used to operate on a single operand.

• ++ Increment
• -- Decrement
• ! Logical negation
• Increment Operators
• Post-increment (a++) – Value is used first, then increased
• Pre-increment (++a) – Value is increased first, then used
• Decrement Operators
• Post-decrement (a--) – Value is used first, then decreased
• Pre-decrement (--a) – Value is decreased first, then used

5. Ternary Operator

      Used to check a condition and return one of two values.

      Syntax:

• condition ? value1 : value2;

6. Conditional (Logical) Operators

     Used to combine multiple conditions.

• && Logical AND

7. Bitwise Operators

     Used to perform operations at the bit level.

• & Bitwise AND
• ^ Bitwise XOR
• ~ Bitwise NOT (Negation)
