迷宫问题java图形界面

你可以使用Java Swing和AWT库来创建迷宫问题的图形界面。以下是一个简单的示例代码：

import java.awt.Color;
import java.awt.Graphics;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.Random;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class MazeGame extends JPanel implements ActionListener {
    private static final long serialVersionUID = 1L;
    private static final int WIDTH = 800;
    private static final int HEIGHT = 600;
    private static final int ROWS = 20;
    private static final int COLS = 20;
    private static final int CELL_SIZE = 30;
    private static final int WALL_THICKNESS = 5;
    private static final Color WALL_COLOR = Color.BLACK;
    private static final Color PATH_COLOR = Color.WHITE;
    private static final Color START_COLOR = Color.GREEN;
    private static final Color END_COLOR = Color.RED;
    private JButton generateButton;
    private int[][] maze;
    private int startRow, startCol, endRow, endCol;

    public MazeGame() {
        setLayout(null);
        generateButton = new JButton("Generate");
        generateButton.setBounds(10, 10, 100, 30);
        generateButton.addActionListener(this);
        add(generateButton);
    }

    public static void main(String[] args) {
        JFrame frame = new JFrame("Maze Game");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(WIDTH, HEIGHT);
        frame.setResizable(false);
        frame.setLocationRelativeTo(null);
        frame.add(new MazeGame());
        frame.setVisible(true);
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == generateButton) {
            generateMaze();
        }
    }

    private void generateMaze() {
        maze = new int[ROWS][COLS];
        Random rand = new Random();
        startRow = rand.nextInt(ROWS);
        startCol = rand.nextInt(COLS);
        endRow = rand.nextInt(ROWS);
        endCol = rand.nextInt(COLS);
        while (endRow == startRow && endCol == startCol) {
            endRow = rand.nextInt(ROWS);
            endCol = rand.nextInt(COLS);
        }
        for (int i = 0; i < ROWS; i++) {
            for (int j = 0; j < COLS; j++) {
                if (i == startRow && j == startCol) {
                    maze[i][j] = 2; // start cell
                } else if (i == endRow && j == endCol) {
                    maze[i][j] = 3; // end cell
                } else {
                    maze[i][j] = rand.nextInt(2); // 0 for wall, 1 for path
                }
            }
        }
        repaint();
    }

    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        g.setColor(WALL_COLOR);
        for (int i = 0; i < ROWS; i++) {
            for (int j = 0; j < COLS; j++) {
                if (maze != null && maze[i][j] == 0) {
                    g.fillRect(j * CELL_SIZE, i * CELL_SIZE, CELL_SIZE, CELL_SIZE);
                }
            }
        }
        g.setColor(PATH_COLOR);
        for (int i = 0; i < ROWS; i++) {
            for (int j = 0; j < COLS; j++) {
                if (maze != null && maze[i][j] == 1) {
                    g.fillRect(j * CELL_SIZE, i * CELL_SIZE, CELL_SIZE, CELL_SIZE);
                }
            }
        }
        if (maze != null) {
            g.setColor(START_COLOR);
            g.fillOval(startCol * CELL_SIZE, startRow * CELL_SIZE, CELL_SIZE, CELL_SIZE);
            g.setColor(END_COLOR);
            g.fillOval(endCol * CELL_SIZE, endRow * CELL_SIZE, CELL_SIZE, CELL_SIZE);
        }
    }
}

这个代码会生成一个20x20的迷宫，其中随机生成起点和终点。点击“Generate”按钮会重新生成迷宫。你可以根据自己的需要调整代码以生成更大或更小的迷宫，或者添加其他功能。
