Thank you for showing us something about the Vector class. Due to the newer Collections framework it is hard to find examples of Vector class usage. C++ programmers are very familiar with Vector. Keep that in mind as I understand Java was based on C.
For the most part, Vector may still be used but many think that it should be deprecated. I am of no opinion here as I have not used it enough yet to understand the inner workings of this class. Many other classes in Java implement Vector and I would be very interested to see how that is done.
Is Vector type-safe? Is it thread-safe? These are questions that I hope more qualified persons can answer.

One quick note: I have used Vector with an iterator in C++. How else could it be done in Java?
Try-catch statements are one big advantage that we have in Java and could be used in case of need for debugging. Also I tried this just to see the result: System.out.println(vc);

The problem is that you inserted the elements as the following strings:

vc.add(”Vector Element #”);

and you printed them out with vc.get(i) which led to them being the following strings:

Vector Object #

You example would have been clearer if you inserted them as “Vector Object #”

Vector progam is working fine when i checked, 6 times vector added so printing 6, tell us the bug in detail

There’s a bug: why You write “System.out.println(”Vector Size :”+vc.size());” and then the output is “ArrayList Size :6″???
Sound me something wrong :S
