Does this help? (from Java api spec):
As of the Java 2 platform v1.2, this class has been retrofitted to implement List, so that it becomes a part of Java's collection framework. Unlike the new collection implementations, Vector is synchronized.
I can only guess that methods that perform structural modifications to the Vector are synchronized (although they are not shown to be in the api spec).

If you look at the actual source for the Vector class you will see that all the methods that touch the array in the Vector are synchronized.

Thank you all! These are really helpful!
