Where as, ArrayList can increase and decrease size dynamically. An Array is a collection of similar items. Where as, ArrayList can hold item of different types. Array is in the System namespace. Where as, ArrayList is in the System. Collections namespace. An Array can have multiple dimensions.

Where as, ArrayList always has exactly one dimension. The List is a child interface of the Collection framework that allows us to maintain the ordered collection of the objects.

We can store the duplicate values and null elements using List. It provides an index-based method to perform the insert, delete, search, update operations on the objects.

The List interface takes place in java. It is also a base of ListIterator classes using which we can iterate the List in forward and backward directions. List interface provides positional access and insertion of elements and preserves the insertion order. The instance of the List can be created using the implementing classes. ArrayList class uses a dynamic array for storing the elements.

The ArrayList class acts like an array, but there is no size limit in it. We can add or remove the elements whenever we want. We can store the duplicate element using the ArrayList class. It manages the order of insertion internally. The ArrayList class is much more flexible than the traditional array. It implements the List interface to use all the methods of List Interface.

It takes place in Java. The elements of it can be randomly accessed. It can not be used for primitive types such as int, char, etc. Save Article. Improve Article. Like Article. Next Array vs ArrayList in Java. Recommended Articles. Article Contributed By :. Easy Normal Medium Hard Expert.
