Generics only work for reference type (anything that is an Object).
Primitive int isn't a reference type.
int[] is, as any array is also an Object.
The proper way to deal with multiple int values is to either use just int[] (not putting them into lists), or to use List. Which one to pick really depends on your exact use case.

I am not able to figure out why ArrayList<int> is not allowed but ArrayList<int[]> is allowed. I was under the impression that primitive data types are not allowed in Collections.
