Documentation

This was the first real problem-solving challenge. The program simulates a tiny library:

Features:
1. Add books to the collection
2. Remove books from the collection          
3. Print the list of available books                    

Concepts Learned:
1. How to work with classes and objects in Java          
2. Using ArrayLists for dynamic storage          
3. Writing methods (addBook, removeBook, listBooks) and calling them

Key Takeaway:
Data structures(like ArrayList) make life way easier compared to plain arrays.

        import java.util.ArrayList;
import java.util.Scanner;

class Book {
    Scanner sc = new Scanner(System.in);
    //attributes
    private String title;

    private String ISBN;

    // Setting up book attributes
    public Book()
    {
        setTitle();

        setISBN();

    }

    public void setTitle() {

        this.title = sc.nextLine();
    }
    public void setAuthor() {
        System.out.println("Enter author: ");
        this.author = sc.nextLine();
    }
    public void setISBN() {
        System.out.println("Enter ISBN: ");
        this.ISBN = sc.nextLine();
    }

    public String getTitle() {
        return title;

    public String getAuthor() {

    //Method to add books to collection
    public void addBook(Book book)

        else{
