Vector were used in old version of java but now a days vector are not used in new version of java.

what is the reason for avoiding the vector in new version ?

What are the updates made in collections in new versions?

Vector is still included in new versions of Java for backwards compatibility with code written with older (pre-1.2) versions. New code should use ArrayList, which is essentially the same thing with a few improvements. The biggest difference is that ArrayList is not synchronized, while Vector is, resulting in a performance improvement when you don't need synchronization.

If you do need a synchronized ArrayList, you can do the following:

List list = Collections.synchronizedList(new ArrayList(...));
