Operators in Java are special symbols or keywords used to perform operations on variables and values. They are fundamental to programming as they allow manipulation of data and control flow. Java categorizes operators into several types, each serving a specific purpose.
Arithmetic Operators
Arithmetic operators perform basic mathematical operations such as addition, subtraction, multiplication, division, and modulus. For example:
int a = 10, b = 3;System.out.println("a + b = " + (a + b)); // Output: 13System.out.println("a % b = " + (a % b)); // Output: 1Copied!✕CopyNote: Division (/) truncates decimal points for integers, and modulus (%) is useful for checking even/odd numbers.
Unary Operators
Unary operators operate on a single operand. Examples include increment (++), decrement (--), negation (-), and logical NOT (!):
int x = 5;System.out.println("Post-increment: " + (x++)); // Output: 5System.out.println("Pre-increment: " + (++x)); // Output: 7Copied!✕CopyLogical NOT (!) inverts a boolean value.
