用Java写一个弹窗式图书管理系统

好的，下面是一个简单的弹窗式图书管理系统的Java代码示例：

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.ArrayList;

public class BookManagementSystem extends JFrame implements ActionListener {

    private JTextField bookNameField, authorField, priceField;
    private JButton addButton, deleteButton, searchButton, displayButton;
    private JTextArea resultArea;

    private ArrayList<Book> bookList;

    public BookManagementSystem() {
        super("图书管理系统");
        bookList = new ArrayList<Book>();

        // UI界面初始化
        JPanel controlPanel = new JPanel(new GridLayout(5, 2, 5, 5));
        controlPanel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));
        controlPanel.add(new JLabel("书名："));
        bookNameField = new JTextField(20);
        controlPanel.add(bookNameField);
        controlPanel.add(new JLabel("作者："));
        authorField = new JTextField(20);
        controlPanel.add(authorField);
        controlPanel.add(new JLabel("价格："));
        priceField = new JTextField(20);
        controlPanel.add(priceField);
        addButton = new JButton("添加");
        addButton.addActionListener(this);
        controlPanel.add(addButton);
        deleteButton = new JButton("删除");
        deleteButton.addActionListener(this);
        controlPanel.add(deleteButton);
        searchButton = new JButton("查询");
        searchButton.addActionListener(this);
        controlPanel.add(searchButton);
        displayButton = new JButton("显示");
        displayButton.addActionListener(this);
        controlPanel.add(displayButton);

        resultArea = new JTextArea(20, 60);
        resultArea.setEditable(false);

        JScrollPane scrollPane = new JScrollPane(resultArea);

        Container container = getContentPane();
        container.add(controlPanel, BorderLayout.NORTH);
        container.add(scrollPane, BorderLayout.CENTER);

        pack();
        setVisible(true);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }

    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == addButton) {
            String bookName = bookNameField.getText();
            String author = authorField.getText();
            double price = Double.parseDouble(priceField.getText());
            Book book = new Book(bookName, author, price);
            bookList.add(book);
            resultArea.setText("添加成功！");
        } else if (e.getSource() == deleteButton) {
            String bookName = bookNameField.getText();
            for (Book book : bookList) {
                if (book.getBookName().equals(bookName)) {
                    bookList.remove(book);
                    resultArea.setText("删除成功！");
                    return;
                }
            }
            resultArea.setText("未找到该书！");
        } else if (e.getSource() == searchButton) {
            String bookName = bookNameField.getText();
            for (Book book : bookList) {
                if (book.getBookName().equals(bookName)) {
                    resultArea.setText(book.toString());
                    return;
                }
            }
            resultArea.setText("未找到该书！");
        } else if (e.getSource() == displayButton) {
            StringBuilder sb = new StringBuilder();
            for (Book book : bookList) {
                sb.append(book.toString()).append("\n");
            }
            resultArea.setText(sb.toString());
        }
    }

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

class Book {
    private String bookName;
    private String author;
    private double price;

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

    public String getBookName() {
        return bookName;
    }

    public void setBookName(String bookName) {
        this.bookName = bookName;
    }

    public String getAuthor() {
        return author;
    }

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

    public double getPrice() {
        return price;
    }

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

    public String toString() {
        return "书名：" + bookName + "，作者：" + author + "，价格：" + price + "元。";
    }
}

这个图书管理系统可以实现添加、删除、查询和显示图书列表的功能。您可以根据您的具体需求进行修改和完善。
