用eclipse做一个图书馆管理系统的源代码

因为图书馆管理系统是一个比较复杂的系统，涉及到多个类和功能，所以这里提供一个简单的示例代码，以供参考：

1. Book类

package model;

public class Book {
    private int id;
    private String name;
    private String author;
    private String publisher;
    private String isbn;
    private boolean isBorrowed;

    public Book(int id, String name, String author, String publisher, String isbn, boolean isBorrowed) {
        this.id = id;
        this.name = name;
        this.author = author;
        this.publisher = publisher;
        this.isbn = isbn;
        this.isBorrowed = isBorrowed;
    }

    // getters and setters
}

2. User类

package model;

public class User {
    private int id;
    private String name;
    private String studentId;
    private String phoneNumber;
    private String password;

    public User(int id, String name, String studentId, String phoneNumber, String password) {
        this.id = id;
        this.name = name;
        this.studentId = studentId;
        this.phoneNumber = phoneNumber;
        this.password = password;
    }

    // getters and setters
}

3. BorrowRecord类

package model;

import java.time.LocalDateTime;

public class BorrowRecord {
    private int id;
    private int bookId;
    private int userId;
    private LocalDateTime borrowTime;
    private LocalDateTime returnTime;

    public BorrowRecord(int id, int bookId, int userId, LocalDateTime borrowTime, LocalDateTime returnTime) {
        this.id = id;
        this.bookId = bookId;
        this.userId = userId;
        this.borrowTime = borrowTime;
        this.returnTime = returnTime;
    }

    // getters and setters
}

4. BookDao类

        for (Book book : books) {
            if (book.getId() == id) {
                books.remove(book);
                return;
            }
        }
    }

    public void updateBook(Book book) {

            if (books.get(i).getId() == book.getId()) {
                books.set(i, book);
                return;
            }
        }
    }

    public Book getBookById(int id) {
        for (Book book : books) {
            if (book.getId() == id) {
                return book;
            }
        }
