In Java, a linked list is a type of data structure that allows the storage and manipulation of elements in a sequence.
The LinkedList class in Java provides a built-in implementation of a linked list.
To add elements to a LinkedList in Java, follow these steps:
Create a LinkedList object
First, create an object of the LinkedList class.
This will create an empty list to which you can add elements.
LinkedList<String> list = new LinkedList<>();
Add elements to the LinkedList
To add elements to the LinkedList, use the add() method.
The add() method adds the specified element to the end of the list.
list.add("Java");
list.add("Python");
list.add("C++");The above code will add three elements to the LinkedList.
Print the elements of the LinkedList
To print the elements of the LinkedList, use a for loop to iterate over the list and print each element.
for (String language : list)
{
System.out.println(language);
}The above code will print the following output:
Java Python C++
The full code to add elements to a LinkedList in Java would look like this:
import java.util.LinkedList;
public class AddElementsToLinkedList
{
public static void main(String[] args)
{
LinkedList<String> list = new LinkedList<>();
list.add("Java"); list.add("Python");
list.add("C++");
for (String language : list)
{
System.out.println(language);In conclusion, adding elements to a LinkedList in Java is a simple process that involves creating a LinkedList object, adding elements using the add() method, and printing the elements using a for loop.
