A method in Java is a block of code inside a class that performs a specific task, and can be called (invoked) when needed. It helps achieve: Code reusability Modularity Readability Encapsulation (keeping logic inside the class)
This project demonstrates Method Overloading in Java with multiple complex cases — covering data type variations, varargs, and type promotions.
This class defines multiple overloaded add() methods, each handling different types or numbers of arguments.
| Method Signature | Description |
|---|---|
int add(int, int) |
Adds two integers |
double add(double, double) |
Adds two doubles |
int add(int, int, int) |
Adds three integers |
int add(int... numbers) |
Adds any number of integers using varargs |
String add(String, String) |
Concatenates two strings |
double add(long, float) |
Demonstrates type promotion |

This file helps you about the what is function which to common to all languages
MethodsShowcase.java is a Java program demonstrating a variety of methods in a single file. It covers:
Instance methods Method overloading Recursion Methods with arrays Varargs (variable number of arguments) Private methods Methods calling other methods
This program is designed as a learning reference for Java beginners to understand different ways to write and use methods.
Using static avoids creating objects For small programs or utility methods, making them static is easier. You can call them directly inside main():
