1. Introduction

The LinkedList class in Java, part of the Collections framework, provides methods to perform operations on linked lists. One common operation is removing an element from a LinkedList. In this blog post, we will explore how to remove elements from a LinkedList in Java.

2. Program Steps

1. Instantiate a LinkedList object and add elements to it.

2. Use the remove method to remove elements from the LinkedList.

3. Display the modified LinkedList to the console.

3. Code Program

import java.util.LinkedList;

public class LinkedListRemoveExample {

    public static void main(String[] args) {

        // Step 1: Instantiate a LinkedList object and add elements to it
        LinkedList<String> animals = new LinkedList<>();
        animals.add("Dog");
        animals.add("Cat");
        animals.add("Horse");
        System.out.println("Original LinkedList: " + animals);

        // Step 2: Use the remove method to remove elements from the LinkedList
        animals.remove("Cat"); // Removes the element "Cat" from the LinkedList

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

Output:

Original LinkedList: [Dog, Cat, Horse]
Modified LinkedList: [Dog, Horse]

4. Step By Step Explanation

Step 1: A LinkedList object named animals is instantiated, and elements "Dog", "Cat", and "Horse" are added to it.

Step 2: The remove method of the LinkedList class is invoked with the parameter "Cat" to remove the element "Cat" from the animals LinkedList.

Step 3: The modified animals LinkedList is displayed to the console, showing that the element "Cat" has been successfully removed, leaving "Dog" and "Horse" in the list.
