Understanding Methods in Java with Simple Example

What is a Method in Java? A method in Java is a block of code that performs a specific task. It helps you reuse code, improve readability, and organize programs. Basic Syntax returnType methodName(parameters) { // method body // code to execute return value; // optional } Example Program public class Calculator{ public static void main(String[] args){ Calculator casio = new Calculator(); casio.add(10,5); casio.sub(10,5); casio.multiply(10,5); casio.div(10,5); } void add(int a,int b){ System.out.println(a+b); } void sub(int a,int b){ System.out.println(a-b); } void multiply(int a,int b){ System.out.println(a*b); } void div(int a,int b){ System.out.println(a/b); } } Output Flow of Execution Program starts in main() Object casio is created Methods are called one by one: add() → prints 15 sub() → prints 5 multiply() → prints 50 div() → prints 2 Program ends Types of Methods in Java 1. Predefined Methods These are already available in Java libraries. Example: System.out.println("Hello"); He
