Methods in Java

Methods are blocks of code that perform a specific task. This tutorial will teach you about declaring, calling, and overloading methods.

Declaring and Calling Methods

To declare a method, use the following syntax:

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

Method Parameters and Return Values

Methods can take parameters and return a value:

public class Main {
    public static void main(String[] args) {
        int result = addNumbers(5, 10);
        System.out.println("Sum: " + result);
    }
    
    public static int addNumbers(int a, int b) {
        return a + b;
    }
}
      

Method Overloading

Method overloading allows you to define multiple methods with the same name but different parameters:

public class Main {
    public static void main(String[] args) {
        System.out.println(addNumbers(5, 10));
        System.out.println(addNumbers(5.5, 10.5));
    }
    
    public static int addNumbers(int a, int b) {
        return a + b;
    }
    
    public static double addNumbers(double a, double b) {
        return a + b;
    }
}
