Arraylist is a child class of AbstractList and implements List interface. It represents dynamic array that can grow or shrink as needed. In case of standard array, one must know the number of elements about to store in advance. In other words, a standard array is fixed in size and its size can’t be changed after its initialisation. To overcome this problem, collection framework provides…

Array Vs Lists in Java (With Examples)

Define List In Java

In Java,  A List is an ordered collection of an object in which values can be stored. It allows insertion, delete, update and positional access elements in list with index number. List created by the following classes(ArrayList, LinkedList , Stack, Vector).

The list method is found in java.util.List package. using this package  we can iterate list in forward and backward directions. The implementation of classes of list are ArrayList, LinkedList, Stack, vector. The arrayList and linkedList are widly uesd in java. The vector class is deprecated scince java5 

How to create a List in JAVA

Implementation of Array List:-

Syntax: List<String> lst1=New ArrayList<>();

Implementation of Linked List:-

Syntax: List<String> lst2=new LinkedList<>();

Different types of Methods of List in Java.

Some of List methods are commonly used in java are:

add() - It is used to add new Element in a list.

addAll()- It is used for add all elements of a list to a new list.

get() - It is used to access any element in a list.

set() - It is used for change element in a List. (More)
