Vector and ArrayList are very similar. Both of them
represent a 'growable array'

arraylist class is added in java/j2ee where has vector class
is before to jdk1.4 they just taken as it as in jdk1.4

the main difference is that Vector it's a synchronized
object, while ArrayList it's not.

for accesing elements of arraylist we can use iterator

for accesing elements of vectorlist we can use both iterator
and enumeraation

arraylist is faster in acessing of elements compared to
vector class

Is passing by reference faster?
