很抱歉,我无法提供完整的代码。但是,我可以给你一些提示和建议,帮助你开始编写这个项目。
首先,你需要定义一些类来表示你的图书馆系统中的不同对象,比如书籍、借阅者和图书管理员。你可以使用类的属性和方法来描述它们的特性和行为。
下面是一个可能的类定义:
```
class Book {
private String title;
private String author;
private int year;
private String isbn;
private boolean available;
public Book(String title, String author, int year, String isbn) {
this.title = title;
this.author = author;
this.year = year;
this.isbn = isbn;
this.available = true;
}
public String getTitle() {
return this.title;
}
public String getAuthor() {
return this.author;
}
public int getYear() {
return this.year;
}
public String getIsbn() {
return this.isbn;
}
public boolean isAvailable() {
return this.available;
}
public void setAvailable(boolean available) {
this.available = available;
}
}
class Borrower {
private String name;
private List<Book> borrowedBooks;
public Borrower(String name) {
this.name = name;
this.borrowedBooks = new ArrayList<>();
}
public String getName() {
return this.name;
}
public void borrowBook(Book book) {
if (book.isAvailable()) {
borrowedBooks.add(book);
book.setAvailable(false);
} else {
System.out.println("This book is not available for borrowing.");
}
}
public void returnBook(Book book) {
if (borrowedBooks.contains(book)) {
borrowedBooks.remove(book);
book.setAvailable(true);
} else {
System.out.println("You did not borrow this book from the library.");
}
}
}
class Librarian {
private String name;
private List<Book> books;
public Librarian(String name) {
this.name = name;
this.books = new ArrayList<>();
}
public String getName() {
return this.name;
}
public void addBook(Book book) {
books.add(book);
}
public void removeBook(Book book) {
books.remove(book);
}
public void displayBooks() {
System.out.println("List of books in the library:");
for (Book book : books) {
System.out.println(book.getTitle() + " by " + book.getAuthor() + " (published in " + book.getYear() + ")");
}
}
}
```
这些类提供了基本的功能,你可以根据需要进行扩展和调整。你还需要编写一个主类来创建对象并调用它们的方法。以下是一个示例:
```
public class LibrarySystem {
public static void main(String[] args) {
Book book1 = new Book("The Great Gatsby", "F. Scott Fitzgerald", 1925, "978-0743273565");
Book book2 = new Book("To Kill a Mockingbird", "Harper Lee", 1960, "978-0446310789");
Book book3 = new Book("1984", "George Orwell", 1949, "978-0451524935");
Borrower borrower1 = new Borrower("Alice");
Borrower borrower2 = new Borrower("Bob");
Librarian librarian = new Librarian("Carol");
librarian.addBook(book1);
librarian.addBook(book2);
librarian.addBook(book3);
borrower1.borrowBook(book1);
borrower2.borrowBook(book2);
borrower2.borrowBook(book3);
librarian.displayBooks();
borrower1.returnBook(book1);
borrower2.returnBook(book3);
librarian.displayBooks();
}
}
```
这个示例程序创建了一个图书馆系统,并演示了一些基本的功能,比如添加书籍、借阅书籍和归还书籍。你可以根据需要修改或扩展它。
希望这些提示和建议能够帮助你开始编写你的Java面向对象图书馆分类项目。
