I'm a bit confused, whether primitive data type arrays, can be considered as objects?

I think the ArrayList in the collection framework only suppose to hold objects.  I am not sure for Arrays.
But in Java 5 version there is a facility like ArrayList also could hold only primitive data types if we declare like following:

ArrayList <Integer> mylist=new ArrayList<Integer>()

An array is an Object in Java. This is true irrespective of its compenent type. The component type of an array may be a primitive type or Object type it does not matter.

You may be surprised to know that the super class of an array is the Object class.

try running this:

int[] ai = new int[1]; System.out.println(ai.getClass().getSuperclass());

You should see the output as:
class java.lang.Object.

This is convincing enouh to say that every array is an object, even if its component type is primitive.

1) Difference between ArrayList & vector?
2) Hass list

First Both are growable array of objects.

Vector is synchronized(bydefault) ArrayList not(if you want Collection.SynchronizedList(list c))

Vector is only growing .but arraylist is shrinking and growing.
