The Collection framework

The Collection framework consists of the interfaces (List, Set, Map) and their subclasses.

You cannot use primitive values for the elements of a Collection.

＜Sample＞

List list = new ArrayList();
for (int i = 0; i <>
    list.add(new Integer(i));
}
for (int i = 0; i <>
    System.out.println(list.get(i));
}
