Answer / vanitha g

1)An array can be of any data type and contain one data
type while array list can contain any data type in the form
of the object.

2)With array you can not dynamically increase or decrease
the size of array dynamically. You must the define the size
of the array. You can change the size of the array with
redim statement but still you have to define type. While
with array list you can make list of any sizes. When a
element or object is added to array list it size is
automatically increase the capacity of the array list.
