Advanced overloading

[swaraj gupta]

public class Bertha {
    static String s = "";
    public static void main(String[] args) {
      int x = 4; Boolean y = true; short[] sa = {1,2,3};
      doStuff(sa, sa);
     System.out.println(s);
   }   
   static void doStuff(Object... o)     { s += "2"; }
   static void doStuff(Integer... i)    { s += "3"; }
   
}

Q. Well m a bit confused about it.., why doStuff(Integer... i) hasnt been called here, though the sa will get autobox to Integer?

Hi and welcome to the JavaRanch.

Please UseCodeTags when posting code. It will highlight your code and make it much easier to read. It probably will also increase the number of people helping you. I'll add them for you since you are new so that you can see the difference.

I would advice you to read this great topic about this matter. If you are still confused then please ask away.

hi wouter, thanks

m still confused...
initially if both the "sa" parameters have been Autoboxed to Integer then why not the method doStuff(Integer...i) has been invoked here..? Please help.

Swaraj, Array ia an Object and not an Integer.
