list - new ArrayList<int>() failing in Java

Question

I have the following code:

List<int> intList = new ArrayList<int>();
for (int index = 0; index < ints.length; index++)
{
    intList.add(ints[index]);
}

It gives me an error...

Syntax error on token "int", Dimensions expected after this token

The error occurs on the line starting with List. Can someone explain why I am getting the error?

Generics in Java are not applicable to primitive types as in int. You should probably use wrapper types such as Integer:

List<Integer> ints = ...

And, to access a List, you need to use ints.get(index).
