编写一个用链表实现的图书管理系统

编写一个图书管理系统，我们可以利用链表数据结构来存储书籍信息。这里是一个简单的概念设计：

1. **书籍类(Book)**: 它可以包含书的基本属性，如书名(title), 作者(author), ISBN(isbn) 和一个指向下一本书的指针(link)。

class Book {
    String title;
    String author;
    String isbn;
    Book next;

    // 构造函数
    public Book(String title, String author, String isbn) {
        this.title = title;
        this.author = author;
        this.isbn = isbn;
        this.next = null;
    }
}

2. **图书管理系统(LibraryManagement)**: 包含一个链表头节点以及基本操作，比如添加新书(addBook)、删除书籍(removeBook)、查找书籍(findBook)和遍历列表(listBooks)等。

class LibraryManagement {
    private Book head;

    // 添加新书
    public void addBook(Book book) {
        if (head == null) {
            head = book;
        } else {
            Book current = head;
            while (current.next != null) {
                current = current.next;
            }
            current.next = book;
        }
    }

    // 删除书籍
    public boolean removeBook(String isbn) {
        if (head == null || head.isbn.equals(isbn)) {
            head = head.next;
            return true;
        }
        Book current = head;
        while (current.next != null && !current.next.isbn.equals(isbn)) {
            current = current.next;
        }
        if (current.next != null) {
            current.next = current.next.next;
            return true;
        }
        return false;
    }

    // 查找书籍
    public Book findBook(String isbn) {
        Book current = head;
        while (current != null) {
            if (current.isbn.equals(isbn)) {
                return current;
            }
            current = current.next;
        }
        return null;
    }

    // 遍历书籍列表
    public void listBooks() {
        Book current = head;
        while (current != null) {
            System.out.println("Title: " + current.title + ", Author: " + current.author);
            current = current.next;
        }
    }
}
