Tutorial: Old and New Vector Methods

The Vector class was updated to implement the List interface.

Tutorial Details:

When the new Collections API was introduced in Java 2 to provide uniform data structure classes, the Vector class was updated to implement the List interface. Use the List methods because they are common to other data structure. If you later decide to use something other than a Vector (eg, ArrayList, or LinkedList, your other code will not need to change.

Even up thru the first several versions of Java 2 (SDK 1.4), the language had not entirely changed to use the new Collections methods. For example, the DefaultListModel still uses the old methods, so if you are using a JList, you will need to use the old method names. There are hints that they plan to change this, but still and interesting omission.
