An array represents a contiguous block of memory where
objects are stored and accessed via a 0-based index value.
Arrays are usually fixed size once they are created.
A java.util.Vector is an implementation of a resizable
array. It has similar functionality as an array but also
gives the advantage of resizability when u try to add
elements to it exceeding its initial size.
The problem is that Vectors are synchronized which is not
necessary for many purposes and this may bring down
performance. Hence the use of ArrayList over Vecotor is
recommended. An ArrayList provides the same functionality of
a Vector, except tat it is not synchronized.
