Java Operators Summary

Java Operators

• Types of Operators:

  • Math: Addition, Subtraction, Division, Multiplication, Modulus

  • Assignment: Assigns values to variables

  • Comparison: Compares values (e.g., greater than, less than)

  • Logical: Evaluates true/false conditions

Mathematical Operators

• Symbols as calculators:

  • + : Addition

  • - : Subtraction

  • / : Division

  • * : Multiplication

  • % : Modulus (remainder of division)

• Order of operations follows PEMDAS.

Assignment Operator

• Assign values using equal sign =.

• Example:

  • int x = 10;

  • x += 5; (increases value)

Comparison Operators

• Symbols:

  • ==: Equal

  • !=: Not equal

  • >: Greater than

  • <: Less than

  • >=: Greater than or equal to

  • <=: Less than or equal to

Logical Operators

• Symbols:

  • &&: And (true if both are true)

  • ||: Or (true if at least one is true)

  • !: Not (reverses boolean value)

• Example usage in conditional checks.
