图书信息应该包含:图书ID、书名、作者姓名、出版社、价格、图书类别(计算机、土木、建筑等)、数量、上架位置、购买日期等。试用面向对象程序设计思想，设计图书管理信息系统，使之能提供以下功能: 1、图书信息录入功能 2、图书信息文件读取功能 3、图书信息文件保存功能网 4、图书信息浏览功能 5、查询功能: 1)按ID查询2)按类型查询 6修改功能: 根据ID修改相应信息

好的，我来给你提供一个简单的Java代码示例：

    }
}

public class BookManagementSystem {
    private List<Book> bookList;

    public BookManagementSystem() {
        bookList = new ArrayList<>();
    }

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

    public void saveToFile(String fileName) {
        try (ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(fileName))) {
            oos.writeObject(bookList);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    }

    public void modifyBook(int id, double price, int quantity, String shelfLocation, Date purchaseDate) {

    }

    public static void main(String[] args) {
        BookManagementSystem system = new BookManagementSystem();

        // add books
        system.addBook(new Book(1, "Head First Java", "Kathy Sierra and Bert Bates", "O'Reilly Media", 49.99, "Computer Science", 10, "A1", new Date()));
        system.addBook(new Book(2, "Clean Code", "Robert C. Martin", "Prentice Hall", 39.99, "Computer Science", 5, "B2", new Date()));
        system.addBook(new Book(3, "Design Patterns", "Erich Gamma, Richard Helm, Ralph Johnson, John Vlissides", "Addison-Wesley Professional", 55.99, "Computer Science", 8, "C3", new Date()));
        system.addBook(new Book(4, "The Pragmatic Programmer", "Andrew Hunt and David Thomas", "Addison-Wesley Professional", 44.99, "Computer Science", 12, "D4", new Date()));

        // save to file
        system.saveToFile("books.dat");

        // read from file
        system.readFromFile("books.dat");

        // display all books
        System.out.println("--- All Books ---");
        system.displayAllBooks();

        // search by ID
        System.out.println("--- Search by ID ---");
        system.searchById(3);

        // search by category
        System.out.println("--- Search by Category ---");
        system.searchByCategory("Computer Science");

        // modify book
        System.out.println("--- Modify Book ---");
        system.modifyBook(4, 49.99, 15, "D4", new Date());
        System.out.println("--- All Books ---");
        system.displayAllBooks();
    }
}

这个代码示例中，Book类表示图书信息，BookManagementSystem类表示了一个简单的图书管理系统，包含了图书信息录入、保存、读取、浏览、查询和修改等功能。

你可以根据自己的需求对代码进行修改和扩展。
