    In Java, a method is a block of code designed to perform a specific task. Methods help in code reusability, modularity, and readability by allowing you to write logic once and use it multiple times. Every method in Java must be declared inside a class and can be either predefined (from Java libraries) or user-defined.

    Basic Syntax:

    modifier static returnType methodName(parameters) {
    // method body
    }

    • modifier: Access level (e.g., public, private).

    • static: Allows calling without creating an object.

    • returnType: Data type of the returned value or void if none.

    • methodName: Follows camelCase naming.

    • parameters: Optional inputs.

    Example: Creating and Calling a Method

    public class Main {
    static void greet() {
    System.out.println("Hello, World!");
    }
    public static void main(String[] args) {
    greet(); // method call
    }
    }
    Copied!

    Output:

    Hello, World!
    Copied!

    Here, greet() is a static method with no parameters and no return value.

    Instance vs Static Methods:

    class Calculator {
    int add(int a, int b) { // instance method
    return a + b;
    }
    static int square(int x) { // static method
    return x * x;
    }
    }
    public class Test {
    public static void main(String[] args) {
    Calculator calc = new Calculator();
    System.out.println(calc.add(5, 3)); // instance call
    System.out.println(Calculator.square(4)); // static call
    }
    }
    Copied!
