Answer / srinivas
Vector is synchronized and compare to array list this slow
access, by defaulst the vector is 10,this is legacy class
Where as arraylist is unsynchronized and fast random
access,in arraylist there is no default size automatically
it is growable once the object is created it will be
allocated,this is advanced class.

If we want to arrange a collection of objects into an other object then we will use either ArrayList or Vector. When we use these classes all the objects that are placed in it will be stored sequentially one after the other.
ArrayList : If we want to store same type of objects then we will use ArrayList class.
Vector : If we want to store different type of objects then we will use Vector class.
