List
So, the List
interface is a part of the Java collections framework and it is used to represent an ordered collection of elements. Elements in a List
interface can be accessed by their position (index) and can include duplicates. Since List
is an interface, it cannot be instantiated. Two commonly used implementations of the List
interface are ArrayList
and LinkedList
. Since these are implementation classes, they can be instantiated. Let’s explore what they are.
ArrayList
ArrayList
is a resizable array-backed implementation of the List
interface. It provides fast random access to elements and is efficient for read-heavy operations. Random access means directly reaching any item using its index quickly.
ArrayList
dynamically resizes itself when elements are added or removed. Adding and removing elements is somewhat slower. LinkedList
is optimized for this.
LinkedList
LinkedList
is an implementation of the List
interface based on a doubly linked list data structure...
