使用Java语言写一套swing图书管理系统

好的，下面是一个简单的Swing图书管理系统的示例代码，包括添加书籍、删除书籍、查找书籍和显示所有书籍等功能。

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

public class BookManagementSystem extends JFrame implements ActionListener {
    private JPanel panel;
    private JLabel titleLabel, authorLabel, yearLabel;
    private JTextField titleText, authorText, yearText;
    private JButton addButton, deleteButton, searchButton, showAllButton;

    private ArrayList<Book> bookList;

    public BookManagementSystem() {
        super("图书管理系统");
        setSize(500, 400);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLayout(new FlowLayout());

        // 初始化图书列表
        bookList = new ArrayList<Book>();

        // 添加图书表单
        panel = new JPanel(new GridLayout(4, 2));
        titleLabel = new JLabel("书名：");
        titleText = new JTextField(20);
        authorLabel = new JLabel("作者：");
        authorText = new JTextField(20);
        yearLabel = new JLabel("出版年份：");
        yearText = new JTextField(20);
        addButton = new JButton("添加");
        addButton.addActionListener(this);
        deleteButton = new JButton("删除");
        deleteButton.addActionListener(this);
        searchButton = new JButton("查找");
        searchButton.addActionListener(this);
        showAllButton = new JButton("显示所有");
        showAllButton.addActionListener(this);

        panel.add(titleLabel);
        panel.add(titleText);
        panel.add(authorLabel);
        panel.add(authorText);
        panel.add(yearLabel);
        panel.add(yearText);
        panel.add(addButton);
        panel.add(deleteButton);
        panel.add(searchButton);
        panel.add(showAllButton);

        add(panel);
        setVisible(true);
    }

    // 处理按钮点击事件
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == addButton) {
            // 添加图书
            String title = titleText.getText();
            String author = authorText.getText();
            int year = Integer.parseInt(yearText.getText());
            Book book = new Book(title, author, year);
            bookList.add(book);
            JOptionPane.showMessageDialog(null, "添加成功！");
        } else if (e.getSource() == deleteButton) {
            // 删除图书
            String title = JOptionPane.showInputDialog("请输入要删除的书名：");
            for (int i = 0; i < bookList.size(); i++) {
                if (bookList.get(i).getTitle().equals(title)) {
                    bookList.remove(i);
                    JOptionPane.showMessageDialog(null, "删除成功！");
                    return;
                }
            }
            JOptionPane.showMessageDialog(null, "未找到该书籍！");
        } else if (e.getSource() == searchButton) {
            // 查找图书
            String title = JOptionPane.showInputDialog("请输入要查找的书名：");
            for (int i = 0; i < bookList.size(); i++) {
                if (bookList.get(i).getTitle().equals(title)) {
                    JOptionPane.showMessageDialog(null, bookList.get(i).toString());
                    return;
                }
            }
            JOptionPane.showMessageDialog(null, "未找到该书籍！");
        } else if (e.getSource() == showAllButton) {
            // 显示所有图书
            StringBuilder sb = new StringBuilder();
            for (int i = 0; i < bookList.size(); i++) {
                sb.append(bookList.get(i).toString() + "\n");
            }
            JOptionPane.showMessageDialog(null, sb.toString());
        }
    }

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

class Book {
    private String title;
    private String author;
    private int year;

    public Book(String title, String author, int year) {
        this.title = title;
        this.author = author;
        this.year = year;
    }

    public String getTitle() {
        return title;
    }

    public String getAuthor() {
        return author;
    }

    public int getYear() {
        return year;
    }

    public String toString() {
        return "书名：" + title + " 作者：" + author + " 出版年份：" + year;
    }
}

这是一个简单的Swing图书管理系统，它使用JFrame和JPanel创建GUI，使用JButton等组件添加各种操作。同时，该系统还创建了一个Book类来存储每本书的信息。
