Using int as a type parameter for java.util.Dictionary

Question

When I try to declare a Dictionary as such:

private Dictionary map;

The compiler gives me the following error:

Answer 1

In Java primitives aren't objects, so you can't use them in place of objects. However Java will automatically box/unbox primitives (aka autoboxing) into objects so you can do things like:

List intList = new LinkedList();
intList.add(1);
intList.add(new Integer(2));
...
Integer first = intList.get(0);
int second = intList.get(1);

But this is really just the compiler automatically converting types for you.
