用java的gui写座位选择系统

好的，座位选择系统可以使用 Java 的 Swing 组件来实现 GUI 界面，以下是一个简单的座位选择系统的示例代码：

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

public class SeatSelectSystem {
    private int rows, cols;
    private boolean[][] seats;
    private ArrayList<int[]> selectedSeats;

    private JFrame frame;
    private JPanel panel;
    private JButton btnConfirm;

    public SeatSelectSystem(int rows, int cols) {
        this.rows = rows;
        this.cols = cols;
        this.seats = new boolean[rows][cols];
        this.selectedSeats = new ArrayList<>();

        this.frame = new JFrame("座位选择系统");
        this.frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        this.panel = new JPanel();
        this.panel.setLayout(new GridLayout(rows, cols));

        for (int i = 0; i < rows; i++) {
            for (int j = 0; j < cols; j++) {
                JButton btnSeat = new JButton("(" + (i+1) + ", " + (j+1) + ")");
                btnSeat.addActionListener(new SeatListener(i, j));
                this.panel.add(btnSeat);
            }
        }

        this.btnConfirm = new JButton("确定");
        this.btnConfirm.addActionListener(new ConfirmListener());

        this.frame.add(this.panel, BorderLayout.CENTER);
        this.frame.add(this.btnConfirm, BorderLayout.SOUTH);
        this.frame.pack();
        this.frame.setVisible(true);
    }

    private class SeatListener implements ActionListener {
        private int row, col;

        public SeatListener(int row, int col) {
            this.row = row;
            this.col = col;
        }

        public void actionPerformed(ActionEvent e) {
            if (!seats[row][col]) {
                JButton btnSeat = (JButton) e.getSource();
                btnSeat.setBackground(Color.GREEN);
                seats[row][col] = true;
                selectedSeats.add(new int[]{row, col});
            } else {
                JButton btnSeat = (JButton) e.getSource();
                btnSeat.setBackground(null);
                seats[row][col] = false;
                selectedSeats.remove(new int[]{row, col});
            }
        }
    }

    private class ConfirmListener implements ActionListener {
        public void actionPerformed(ActionEvent e) {
            if (selectedSeats.size() == 0) {
                JOptionPane.showMessageDialog(frame, "您还未选择座位！", "错误", JOptionPane.ERROR_MESSAGE);
            } else {
                StringBuilder sb = new StringBuilder();
                for (int[] seat : selectedSeats) {
                    sb.append("(").append(seat[0]+1).append(", ").append(seat[1]+1).append("), ");
                }
                String seatStr = sb.substring(0, sb.length()-2);
                JOptionPane.showMessageDialog(frame, "您已成功选择座位：" + seatStr, "选座成功", JOptionPane.INFORMATION_MESSAGE);
            }
        }
    }

    public static void main(String[] args) {
        SeatSelectSystem system = new SeatSelectSystem(5, 8);
    }
}

这个座位选择系统使用了 Swing 的 JButton 组件来实现座位按钮，并在用户点击座位时改变按钮的背景颜色，同时记录用户选择的座位。用户点击“确定”按钮后，检查用户是否选择了座位，并将用户选择的座位信息以弹窗形式展示给用户。
