What is difference between Array and ArrayList? code example

Example 1: Difference between Array vs ArrayList

Arrays are fixed size
ArrayList's size auotomatically adjusted
Arrays can hold primitives and object
ArrayList can hold only objects
Arrays can be multi dimensional
ArrayList cannot be multi-dimentional
Array is a build in data structure
ArrayList is implementing class of List interface in Collection framework

Example 2: java difference between array and list

In general (and in Java) an array is a data structure generally
consisting of sequential memory storing a collection of objects.

List is an interface in Java, which means that it may have multiple
implementations. One of these implementations is ArrayList, which
is a class that implements the behavior of the List interface using
arrays as the data structure.
