First difference: array is already with fixed size while array lists size could be dynamically changed.

Secondly, array can include only the same type of data while array list can consist of different primitive data types as well as objects.

Array is collection of similar data type values. We cant resizable and growable of array. It is already fixed when you declared while array list works as a dynamic in which size could be grow. It is a part of collection framework to handle or store the collection of object not any type of values.
