Jason,
As per my understanding, an ArrayList<String> will help generating
compilation errors should one try to add a non String object to the list.
It does not mean that you can not add a non String object to the underlying
list. For e.g. the following code does not result in an error:
public static void main(String[] args) {
ArrayList<String> sl = new ArrayList<String>();
sl.add("Me");
((ArrayList)sl).add(new Integer(10));
System.out.println(sl);
}
