Why can't I pass a short array to java for a method that takes an int array?

Question

I have a method that takes an int [] parameter. I want to give him a lot of shorts. But all I get is "incompatible types: short [] cannot be converted to int []". Why is this? example:

short[] arr = new short[2];
arr[0] = 8;
arr[1]=9;
example(arr);

example(int[] anArray){
}

As far as I know, the abbreviation from int is just expanding, so it should be automatically entered, right? How to convey it then? Thank.
