Java Var args Method - Syntax and Declaration (Part - 2)

In this tutorial we’re going to look at Syntax & Declaration of Var-args Method in Java programming language in detail and how to declare and define a Var args method and how to call var args methods in Java as well as explain the role of Ellipsis(…) three dots in it with simple program .

You may ask why we need it. Where it is useful?

Let me explain you first, Problem until Java 4.0.

1. We cannot declare a method with variable number of arguments.
2. If there is a change in a number of arguments then compulsory we should declare a new method, which increases the length of code and reduces readability.

So, to overcome this problem “SUN” people introduced var-args method concept in Java 5.0 or jdk1.5 version that are explained it with programs.

In my next tutorial, I will discuss about Var args method some internal details and how to access values from var args parameter.
