Methods with Variable Arguments List :

With java 5, you can have a function with variable number of arguments (called for short: var-args) , you do this following the rules below :
1.Specify the type of arguments (can be primitive or Object).
2.Use the (…) syntax.
3. You can have other arguments with var-arg .
4.You can have only one var-arg .
5.The var-arg must be last on in method arguments.

See the following example :

Code:: public class VariableArg { public static void main(String args[]) { int output = sum(1,2,4,5,1,3); System.out.println("Sum = "+output); } public static int sum(int ... x) { int result =0 ; for (int i=0;i<x.length;i++) { result+=x[i]; } return result; } }

The output is :

Code:: Sum = 16
