用java写一个基于java swing的图书管理系统

好的，以下是一个简单的基于Java Swing的图书管理系统示例：

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

public class LibraryManagementSystem extends JFrame implements ActionListener {
    private JLabel headerLabel;
    private JPanel mainPanel;
    private JTextField titleField, authorField, yearField;
    private JButton addButton, removeButton, updateButton;
    private JTable table;
    private DefaultTableModel model;

    private ArrayList<Book> books;

    public LibraryManagementSystem() {
        super("图书管理系统");

        // 初始化图书列表
        books = new ArrayList<>();
        books.add(new Book("《Java编程思想》", "Bruce Eckel", "2002"));
        books.add(new Book("《Java核心技术》", "Cay S. Horstmann", "2016"));
        books.add(new Book("《深入浅出设计模式》", "程杰", "2015"));

        // 初始化界面
        initUI();

        setSize(600, 400);
        setLocationRelativeTo(null);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setVisible(true);
    }

    private void initUI() {
        // 创建标题
        headerLabel = new JLabel("图书列表");
        headerLabel.setFont(new Font("微软雅黑", Font.BOLD, 20));
        headerLabel.setHorizontalAlignment(SwingConstants.CENTER);

        // 创建表格
        model = new DefaultTableModel();
        model.addColumn("书名");
        model.addColumn("作者");
        model.addColumn("出版年份");
        for (Book book : books) {
            model.addRow(new Object[]{book.getTitle(), book.getAuthor(), book.getYear()});
        }
        table = new JTable(model);

        // 创建添加按钮
        addButton = new JButton("添加");
        addButton.addActionListener(this);

        // 创建删除按钮
        removeButton = new JButton("删除");
        removeButton.addActionListener(this);

        // 创建更新按钮
        updateButton = new JButton("更新");
        updateButton.addActionListener(this);

        // 创建输入框和标签
        titleField = new JTextField();
        authorField = new JTextField();
        yearField = new JTextField();
        JLabel titleLabel = new JLabel("书名：");
        JLabel authorLabel = new JLabel("作者：");
        JLabel yearLabel = new JLabel("出版年份：");

        // 创建主面板
        mainPanel = new JPanel(new BorderLayout());
        JPanel topPanel = new JPanel(new GridLayout(2, 3, 5, 5));
        topPanel.add(titleLabel);
        topPanel.add(titleField);
        topPanel.add(addButton);
        topPanel.add(authorLabel);
        topPanel.add(authorField);
        topPanel.add(removeButton);
        topPanel.add(yearLabel);
        topPanel.add(yearField);
        topPanel.add(updateButton);
        mainPanel.add(headerLabel, BorderLayout.NORTH);
        mainPanel.add(new JScrollPane(table), BorderLayout.CENTER);
        mainPanel.add(topPanel, BorderLayout.SOUTH);

        // 添加主面板到窗口中
        add(mainPanel);
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == addButton) {
            // 添加新书
            String title = titleField.getText();
            String author = authorField.getText();
            String year = yearField.getText();
            if (!title.isEmpty() && !author.isEmpty() && !year.isEmpty()) {
                books.add(new Book(title, author, year));
                model.addRow(new Object[]{title, author, year});
                titleField.setText("");
                authorField.setText("");
                yearField.setText("");
            }
        } else if (e.getSource() == removeButton) {
            // 删除选中的书
            int[] selectedRows = table.getSelectedRows();
            for (int i = selectedRows.length - 1; i >= 0; i--) {
                books.remove(selectedRows[i]);
                model.removeRow(selectedRows[i]);
            }
        } else if (e.getSource() == updateButton) {
            // 更新选中的书
            int row = table.getSelectedRow();
            if (row >= 0) {
                String title = titleField.getText();
                String author = authorField.getText();
                String year = yearField.getText();
                if (!title.isEmpty() && !author.isEmpty() && !year.isEmpty()) {
                    Book book = books.get(row);
                    book.setTitle(title);
                    book.setAuthor(author);
                    book.setYear(year);
                    model.setValueAt(title, row, 0);
                    model.setValueAt(author, row, 1);
                    model.setValueAt(year, row, 2);
                }
            }
        }
    }

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

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

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

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getAuthor() {
        return author;
    }

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

    public String getYear() {
        return year;
    }

    public void setYear(String year) {
        this.year = year;
    }
}

这个图书管理系统使用了Java Swing库来创建界面，可以添加、删除和更新图书。它包含一个Book类来表示每个书籍的属性，并使用一个ArrayList来存储所有的书籍。控制器是LibraryManagementSystem类，负责处理用户与图书列表的交互并更新界面。
