java弹窗表格实现管理员对图书的查询和修改，不用数据库

可以使用Java的Swing组件来实现管理员对图书的查询和修改，并且不用数据库。具体来说，可以使用JTable组件来实现表格的显示和编辑，使用JOptionPane组件来实现弹窗的显示。以下是简单的示例代码：

import javax.swing.*;
import javax.swing.table.DefaultTableModel;
import java.awt.*;
import java.util.ArrayList;

public class BookManager {
    private ArrayList<Book> books;

    public BookManager() {
        books = new ArrayList<Book>();
    }

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

    public ArrayList<Book> searchBook(String keyword) {
        ArrayList<Book> results = new ArrayList<Book>();
        for (Book book : books) {
            if (book.getTitle().contains(keyword) || book.getAuthor().contains(keyword)) {
                results.add(book);
            }
        }
        return results;
    }

    public void modifyBook(Book book) {
        int index = books.indexOf(book);
        if (index != -1) {
            books.set(index, book);
        }
    }

    public static void main(String[] args) {
        BookManager manager = new BookManager();
        JFrame frame = new JFrame("图书管理系统");
        frame.setSize(800, 600);
        frame.setLocationRelativeTo(null);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JPanel panel = new JPanel(new BorderLayout());
        JTable table = new JTable(new DefaultTableModel(new Object[] {"书名", "作者", "出版社", "价格"}, 0));
        JScrollPane scrollPane = new JScrollPane(table);
        panel.add(scrollPane, BorderLayout.CENTER);
        JPanel buttonPanel = new JPanel();
        JButton addButton = new JButton("添加图书");
        addButton.addActionListener(e -> {
            String title = JOptionPane.showInputDialog(frame, "请输入书名：");
            String author = JOptionPane.showInputDialog(frame, "请输入作者：");
            String publisher = JOptionPane.showInputDialog(frame, "请输入出版社：");
            double price = Double.parseDouble(JOptionPane.showInputDialog(frame, "请输入价格："));
            Book book = new Book(title, author, publisher, price);
            manager.addBook(book);
            DefaultTableModel model = (DefaultTableModel) table.getModel();
            model.addRow(new Object[] {book.getTitle(), book.getAuthor(), book.getPublisher(), book.getPrice()});
        });
        buttonPanel.add(addButton);
        JButton searchButton = new JButton("查询图书");
        searchButton.addActionListener(e -> {
            String keyword = JOptionPane.showInputDialog(frame, "请输入关键字：");
            ArrayList<Book> results = manager.searchBook(keyword);
            if (results.size() == 0) {
                JOptionPane.showMessageDialog(frame, "未找到相关图书！");
            } else {
                DefaultTableModel model = (DefaultTableModel) table.getModel();
                model.setRowCount(0);
                for (Book book : results) {
                    model.addRow(new Object[] {book.getTitle(), book.getAuthor(), book.getPublisher(), book.getPrice()});
                }
            }
        });
        buttonPanel.add(searchButton);
        JButton modifyButton = new JButton("修改图书");
        modifyButton.addActionListener(e -> {
            int row = table.getSelectedRow();
            if (row == -1) {
                JOptionPane.showMessageDialog(frame, "请先选择要修改的图书！");
                return;
            }
            String title = JOptionPane.showInputDialog(frame, "请输入书名：", table.getValueAt(row, 0));
            String author = JOptionPane.showInputDialog(frame, "请输入作者：", table.getValueAt(row, 1));
            String publisher = JOptionPane.showInputDialog(frame, "请输入出版社：", table.getValueAt(row, 2));
            double price = Double.parseDouble(JOptionPane.showInputDialog(frame, "请输入价格：", table.getValueAt(row, 3)));
            Book book = new Book(title, author, publisher, price);
            manager.modifyBook(book);
            DefaultTableModel model = (DefaultTableModel) table.getModel();
            model.setValueAt(book.getTitle(), row, 0);
            model.setValueAt(book.getAuthor(), row, 1);
            model.setValueAt(book.getPublisher(), row, 2);
            model.setValueAt(book.getPrice(), row, 3);
        });
        buttonPanel.add(modifyButton);
        panel.add(buttonPanel, BorderLayout.SOUTH);
        frame.setContentPane(panel);
        frame.setVisible(true);
    }
}

class Book {
    private String title;
    private String author;
    private String publisher;
    private double price;

    public Book(String title, String author, String publisher, double price) {
        this.title = title;
        this.author = author;
        this.publisher = publisher;
        this.price = price;
    }

    public String getTitle() {
        return title;
    }

    public String getAuthor() {
        return author;
    }

    public String getPublisher() {
        return publisher;
    }

    public double getPrice() {
        return price;
    }

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

    public String toString() {
        return "书名：" + title + "，作者：" + author + "，出版社：" + publisher + "，价格：" + price;
    }
}

这个示例代码实现了一个简单的图书管理系统，其中BookManager类负责管理图书信息，包括添加、查询和修改，Book类代表图书实体，包括书名、作者、出版社和价格等属性。在程序运行时，通过Swing组件构建了一个包含表格和按钮的窗口，用户可以通过按钮进行相应的操作。由于图书信息存储在内存中的ArrayList中，所以不需要使用数据库。
