Swapping Two Random Strings in Java LinkedList

Are you struggling to swap two random strings in a LinkedList within Java? If you already know how to handle integers but find strings a bit more challenging, you’re not alone! In this guide, we'll explore the process step by step.

Understanding the Problem

When working with data structures like LinkedLists, sometimes we need to manipulate the data stored within them. One common operation is swapping the positions of two elements. In this case, we want to swap two random strings that the user inputs from the keyboard.

Step-by-Step Guide to Swapping Strings

Let’s break down the solution into manageable parts. We’ll cover how to take user input, store it in a LinkedList, and then swap two random strings.

Step 1: Setting Up Your Java Environment

Before you start, ensure you have Java installed on your system. You can write your code in any IDE or a simple text editor.

Step 2: Import Required Classes

At the beginning of your Java file, import the following classes to utilize LinkedList and generate random numbers:

Step 3: Create Your LinkedList and Take User Input

You need to initialize a LinkedList and a Scanner object to take user input. Here’s how to do it:

Step 4: Display the Original List

After collecting the data, it’s helpful to display the original contents of the LinkedList. This will help you visualize the changes made during the swap.

Step 5: Generate Random Indices for Swapping

Next, we need to determine which two strings to swap. This involves generating two different random indices:
