How to Initialize List Object in Java

Java is an object-oriented programming language that is widely used for developing applications.

A list is a data structure in Java that is used to store elements in a specific order.

In this article, we will learn how to initialize a List object in Java.

Different Ways to Initialize a List Object in Java

There are several ways to initialize a List object in Java, and they are as follows:

Using the ArrayList class

The ArrayList class is a part of the Java Collection framework and is used to store a collection of elements in a dynamic array. Here is an example of how to initialize an ArrayList object:

import java.util.ArrayList;

public class Main {
public static void main(String[] args) {
ArrayList list = new ArrayList();
list.add("Java");
list.add("Python");
list.add("C++");
System.out.println(list);
}
}

Using the LinkedList class

The LinkedList class is a part of the Java Collection framework and is used to store a collection of elements in a linked list.

Here is an example of how to initialize a LinkedList object:

import java.util.LinkedList;

public class Main {
public static void main(String[] args) {
LinkedList list = new LinkedList();
list.add("Java");
list.add("Python");
list.add("C++");
System.out.println(list);
}
}

Using Arrays.asList() method

The Arrays.asList() method is used to initialize a List object from an array of elements.

Here is an example of how to use this method:

import java.util.Arrays;
import java.util.List;

public class Main {
public static void main(String[] args) {
List list = Arrays.asList("Java", "Python", "C++");
System.out.println(list);
}
}
