1. Introduction

In Java, LinkedList is a part of the Collection framework present in java.util package. This class is an implementation of the LinkedList data structure which is a linear data structure where the elements are not stored in contiguous locations and every element is a separate object with a data part and address part. In this guide, we will demonstrate how to add elements to a LinkedList in Java.

2. Program Steps

1. Create a LinkedList object.

2. Use the add method to add elements to the LinkedList.

3. Display the LinkedList to the console.

3. Code Program

import java.util.LinkedList;

public class LinkedListExample {

    public static void main(String[] args) {

        // Step 1: Create a LinkedList object
        LinkedList<String> animals = new LinkedList<>();

        // Step 2: Use the add method to add elements to the LinkedList
        animals.add("Dog");
        animals.add("Cat");
        animals.add("Horse");

        // Step 3: Display the LinkedList to the console
        System.out.println("LinkedList: " + animals);
    }
}

Output:

LinkedList: [Dog, Cat, Horse]

4. Step By Step Explanation

Step 1: A LinkedList object named animals is created to store String elements.

Step 2: The add method of the LinkedList class is used to add String elements "Dog", "Cat", and "Horse" to the animals LinkedList.

Step 3: The contents of the animals LinkedList are displayed to the console, showing the elements that were added.
