Difference between Array and Arraylist

Array Vs Array List In Java :

Array	Array List
Arrays are static in nature. Arrays are fixed length data structures. You can’t change their size once they are created.	Array List is dynamic in nature. Its size is automatically increased if you add elements beyond its capacity.
Arrays can hold both primitives as well as objects.	Array List can hold only objects.
Arrays can be iterated only through for loop or for-each loop.	Array List provides iterators to iterate through their elements.
The size of an array is checked using length attribute.	The size of an Array List can be checked using size() method.
Array gives constant time performance for both add and get operations.	Array List  also gives constant time performance for both add and get operations provided adding an element doesn’t trigger resize.
Arrays don’t support generics.	Array List supports generics.
Arrays are not type safe.	Array List are type safe.
Arrays can be multi-dimensional.	Array List can’t be multi-dimensional.
Elements are added using assignment operator.	Elements are added using add() method.
