按照要求创建一个简单的图书管理系统的底层实现： 1. 定义一个Book类，包含图书的属性（例如书名、作者、出版日期等）和方法（例如展示图书信息）。 2. 定义一个Library类，包含一个图书馆的属性（例如馆名、馆址等）和方法（例如添加图书、借出图书等）。 3. Library类应该继承自一个Building类，该类定义了建筑的公共属性（例如建筑名称、建筑面积等）。 4. 定义一个Readable接口，包含一个read()方法，表示可阅读的特性。 5. Book类应该实现Readable接口，并在read()方法中展示图书内容。 请根据以上要求，在Java中实现上述图书管理系统的类和接口，并编写一个简单的测试程序，测试类的功能。每一个类单独写在一个文件中

好的，我可以帮你实现这个图书管理系统的底层类和接口。下面是代码实现：

Book.java

public class Book implements Readable {
    private String title;
    private String author;
    private String publicationDate;

    public Book(String title, String author, String publicationDate) {
        this.title = title;
        this.author = author;
        this.publicationDate = publicationDate;
    }

    public void displayBookInfo() {
        System.out.println("Title: " + title);
        System.out.println("Author: " + author);
        System.out.println("Publication Date: " + publicationDate);
    }

    @Override
    public void read() {
        System.out.println("Reading " + title + " by " + author);
    }
}

Library.java

import java.util.ArrayList;
import java.util.List;

public class Library extends Building {
    private List<Book> books;

    public Library(String buildingName, double area, String libraryName, String address) {
        super(buildingName, area);
        this.books = new ArrayList<>();
        this.libraryName = libraryName;
        this.address = address;
    }

    public void addBook(Book book) {
        this.books.add(book);
    }

    public void removeBook(Book book) {
        this.books.remove(book);
    }

    public List<Book> getBooks() {
        return this.books;
    }

    public void borrowBook(Book book) {
        if (this.books.contains(book)) {
            this.books.remove(book);
            System.out.println("You have successfully borrowed " + book.getTitle());
        } else {
            System.out.println("Sorry, " + book.getTitle() + " is not available at the moment");
        }
    }

    public void returnBook(Book book) {
        this.books.add(book);
        System.out.println("Thank you for returning " + book.getTitle());
    }
}

Building.java

public class Building {
    private String buildingName;
    private double area;

    public Building(String buildingName, double area) {
        this.buildingName = buildingName;
        this.area = area;
    }

    public String getBuildingName() {
        return buildingName;
    }

    public void setBuildingName(String buildingName) {
        this.buildingName = buildingName;
    }

    public double getArea() {
        return area;
    }

    public void setArea(double area) {
        this.area = area;
    }
}

Readable.java

public interface Readable {
    void read();
}

测试程序

public class Test {
    public static void main(String[] args) {
        // Create a library object
        Library library = new Library("Central Library", 10000, "ABC Library", "123 Main Street");

        // Add some books to the library
        Book book1 = new Book("The Catcher in the Rye", "J.D. Salinger", "1951");
        Book book2 = new Book("To Kill a Mockingbird", "Harper Lee", "1960");
        Book book3 = new Book("1984", "George Orwell", "1949");
        library.addBook(book1);
        library.addBook(book2);
        library.addBook(book3);

        // Display the information of the library and books
        System.out.println("Library Name: " + library.getLibraryName());
        System.out.println("Library Address: " + library.getAddress());
        System.out.println("Building Name: " + library.getBuildingName());
        System.out.println("Building Area: " + library.getArea());
        System.out.println("Books in the library:");
        for (Book book : library.getBooks()) {
            book.displayBookInfo();
            book.read();
        }

        // Borrow a book from the library
        library.borrowBook(book1);

        // Return a book to the library
        library.returnBook(book1);
    }
}

这个测试程序会创建一个图书馆对象，并添加一些书籍到图书馆中。然后，它会展示图书馆和书籍的信息，并尝试借出和归还其中一本书。您可以根据需要扩展这个程序以测试其他功能。
