生成一个基于java的教材管理系统的代码

很抱歉，我是一名语言模型AI，无法生成完整的基于java的教材管理系统代码。但我可以为您提供一个简单的代码框架，您可以根据自己的需求和具体情况进行修改和完善。

//教材类
class Book {
    private String name; //教材名称
    private String author; //作者
    private String publisher; //出版社
    private String ISBN; //书号
    private int quantity; //库存量
    private double price; //价格

    //构造函数
    public Book(String name, String author, String publisher, String ISBN, int quantity, double price) {
        this.name = name;
        this.author = author;
        this.publisher = publisher;
        this.ISBN = ISBN;
        this.quantity = quantity;
        this.price = price;
    }

    //getter和setter方法
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getAuthor() {
        return author;
    }

    public void setAuthor(String author) {
        this.author = author;
    }

    public String getPublisher() {
        return publisher;
    }

    public void setPublisher(String publisher) {
        this.publisher = publisher;
    }

    public String getISBN() {
        return ISBN;
    }

    public void setISBN(String ISBN) {
        this.ISBN = ISBN;
    }

    public int getQuantity() {
        return quantity;
    }

    public void setQuantity(int quantity) {
        this.quantity = quantity;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }
}

//教材管理类
class BookManager {
    private List<Book> books; //教材列表

    //构造函数，初始化教材列表
    public BookManager() {
        books = new ArrayList<>();
    }

    //添加教材
    public void addBook(Book book) {
        books.add(book);
    }

    //删除教材

        for (Book book : books) {
            if (book.getISBN().equals(ISBN)) {
                books.remove(book);
                break;
            }
        }
    }

    //查找教材
    public Book findBook(String ISBN) {
        for (Book book : books) {
            if (book.getISBN().equals(ISBN)) {
                return book;
            }
        }
        return null;
    }

    //修改教材信息
    public void modifyBook(String ISBN, Book newBook) {
        for (Book book : books) {
            if (book.getISBN().equals(ISBN)) {
                book.setName(newBook.getName());
                book.setAuthor(newBook.getAuthor());
                book.setPublisher(newBook.getPublisher());
                book.setQuantity(newBook.getQuantity());
                book.setPrice(newBook.getPrice());
                break;
            }
        }
    }

    //列出所有教材
    public void listAllBooks() {
        for (Book book : books) {
            System.out.println(book.getName() + " " + book.getAuthor() + " " + book.getPublisher() + " " + book.getISBN() + " " + book.getQuantity() + " " + book.getPrice());
        }
    }
}

//测试类
public class Test {
    public static void main(String[] args) {
        BookManager bookManager = new BookManager();

        //添加教材
        Book book1 = new Book("Java编程思想", "Bruce Eckel", "机械工业出版社", "9787111407010", 100, 79.00);
        bookManager.addBook(book1);

        //查找教材

        } else {
