some answers from "Java In a Nutshell"
(David Flanagan ,Publisher: O'Reilly)
In Java 1.2, the new Iterator interface is preferred over Enumeration.
Vector is quite similar to the ArrayList class,
except that the methods of Vector are synchronized,
which makes them thread-safe but increases the overhead of calling them.
If you need thread safety or need to be compatible with Java 1.0 or Java 1.1, use Vector;
otherwise, use ArrayList.
