/*

* It stands for variable argument methods.

* In java language, if we have variable number of arguments, then copulsorily new method has to be written till jdk 1.4v

* But jdk 1.5v we can write single method which can handle variable number of arguments

* but all of them should be of same type.

*

* Internally var-arg method will convert to SingleDimension array so we can

* access the var arg method arguments using index

*

* Syntax:- methodName(dataType... variableName)

//Example:-

class Sum

{

public void add(int... x)

{

int total=0;

for(int i=0;i<x.length;i++)

{

total+=x[i];

}

System.out.println("Sum is: "+total);

}

}

public class First {

public static void main(String[] args) {

Sum s=new Sum();

s.add();

s.add(10);

s.add(10,20);

s.add(10,20,30);

}
