application in Java for managing a library's collection of books and understand how each part connects. The features needed to implement are:

$1$

$.$

$$The ability to add new books to the collection from a text file where each book has a unique ID number, title, and author.

$2$

$.$

$$The ability to remove a book from the collection using its ID number.

$3$

$.$

$$The ability to list all books currently in the collection.

The text file should be formatted as follows: each line represents a book, and the id

$,$

$$title$,$ and author are separated by a comma. For instance:

$1$

$.$

To Kill a Mockingbird,Harper Lee

$2$

$.$

$1$

$9$

$8$

$4$

$,$

George Orwell

$3$

$.$

The Great Gatsby,F

$.$

$$Scott Fitzgeralde

answer these questions based on the text above. Define Requirements: Create a document where you describe the features and functionality of the software in detail. This includes understanding who the system's users are, what tasks they will perform, and under what constraints the software must operate.

Gather Requirements: Interact with potential users $($or use your imagination to role$-$play as a user$)$ to understand their needs and desires for the system. In this case, describe the intended users of the system and how they would interact with its features.

Implementation Plan: Break down the overall problem into smaller tasks that can be developed and tested separately. Determine the order in which these tasks should be tackled. Your plan should include the classes and methods that will need to be written. Include their arguments, return values, and algorithms used.

Testing Plan: Describe how you will test your code to ensure it works.
