how to stop "array may not be initialized" warning

my class has an array of ints named "calls" and an int "calls_size" to keep track of it's size. I know this screams for a Vector but I think it is a pain in the butt using a vector for ints, too much screwing around with Object nonsense

anyway, this function should return an array of ints matching "calls" but with "calls_size" at the begining, so if calls==10,11,12 then results=3,10,11,12

it has been awhile since I have used java, especially with arrays, so I'm not sure if my whole open ended array idea will work, but at any rate, line 06 gives me a compilation error:  "variable results might not have been initialized".
I am quite aware of this fact and I don't care if it is initialized or not since I am manually tracking the size. This error stops compilation, however. Is there any way to demote the error to simply a warning? Any suggestions regarding my scheme would also be welcomed.

01 public int[] getCalls()
02 {
03    try
04    {
05        int[] results;
06        results[0] = calls_size;
07        for(int i = 1; i <= calls_size; i++)
08        {
09            results[i] = calls[i];
10        }
11        return results;
12   }
   ...snip ...
