Sample Problem and Its Solution

Problem: Designing a Simple Library System

Create a Java program in BlueJ that models a library, allowing users to add books, display available books, and borrow books.

Solution Outline

1. Identify Classes: Library, Book, User
2. Design Class Attributes:
   • Library: list of books, list of users
   • Book: title, author, ISBN, availability status
   • User: name, borrowed books
3. Implement Classes:

Sample Code Snippet for Book Class

```java

public class Book {

private String title;

private String author;

private String ISBN;

private boolean isAvailable;

public Book(String title, String author, String ISBN) {

this.title = title;

this.author = author;

this.ISBN = ISBN;

this.isAvailable = true;

}

public String getTitle() {

return title;

}

public boolean isAvailable() {

return isAvailable;

}

public void borrowBook() {

if (isAvailable) {

isAvailable = false;

} else {

System.out.println("Book is already borrowed.");

}

}

public void returnBook() {

isAvailable = true;

}

}

```

Implementing the Library Class

```java

import java.util.ArrayList;

public class Library {

private ArrayList books;

public Library() {

books = new ArrayList<>();

}

public void addBook(Book book) {

books.add(book);

System.out.println("Book added: " + book.getTitle());

}

public void displayBooks() {

for (Book b : books) {

String status = b.isAvailable() ? "Available" : "Borrowed";

System.out.println(b.getTitle() + " by " + b.getAuthor() + " - " + status);

}

}

public void borrowBook(String title) {

for (Book b : books) {

if (b.getTitle().equalsIgnoreCase(title) && b.isAvailable()) {

b.borrowBook();

System.out.println("You have borrowed: " + b.getTitle());

return;

}

}

System.out.println("Book not available or not found.");

}

}

```
