In java J2SE0.5 you can now make a function with a variable number of paramters. The rules to do that is :

- Only varaible paramter list only .
- varaible paramter list must apper in the last inside the parentheses of the function.
- defined as : type followed by three dots and the name .

And example about method with a variable number of parameters.

Code:

 import java.io.*;
 class MyClass {
 public void printStuff(String greet, int... values) {
 for (int v : values ) {
 System.out.println( greet + ":" + v);
 }
 }
 }
 class VarargTest {
 public static void main(String[] args) {
 MyClass mc = new MyClass();
 mc.printStuff("Hello", 1);
 mc.printStuff("Hey", 1,2);
 mc.printStuff("Hey you", 1,2,3);
 }
 }
