给出以上实现的Java代码

以下是一个简单的Java代码示例，演示了推箱子游戏的基本逻辑和图形界面交互：

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

public class PushBoxGame extends JFrame {
    private static final long serialVersionUID = 1L;
    private GridButton[][] gridButtons;
    private int playerRow;
    private int playerCol;

    public PushBoxGame(int rows, int cols) {
        setTitle("推箱子游戏");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setResizable(false);

        Container container = getContentPane();
        container.setLayout(new GridLayout(rows, cols));

        gridButtons = new GridButton[rows][cols];
        for (int row = 0; row < rows; row++) {
            for (int col = 0; col < cols; col++) {
                GridButton button = new GridButton(row, col);
                button.addActionListener(new ButtonClickListener());
                container.add(button);
                gridButtons[row][col] = button;
            }
        }

        pack();
        setLocationRelativeTo(null);
        setVisible(true);
    }

    private void updateGridButton(int row, int col, String text) {
        gridButtons[row][col].setText(text);
    }

    private void movePlayer(int newRow, int newCol) {
        updateGridButton(playerRow, playerCol, ".");
        playerRow = newRow;
        playerCol = newCol;
        updateGridButton(playerRow, playerCol, "P");
    }

    private void moveBox(int oldRow, int oldCol, int newRow, int newCol) {
        updateGridButton(oldRow, oldCol, ".");
        updateGridButton(newRow, newCol, "B");
    }

    private class GridButton extends JButton {
        private static final long serialVersionUID = 1L;
        private int row;
        private int col;

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

        public int getRow() {
            return row;
        }

        public int getCol() {
            return col;
        }
    }

    private class ButtonClickListener implements ActionListener {
        @Override
        public void actionPerformed(ActionEvent e) {
            GridButton button = (GridButton) e.getSource();
            int buttonRow = button.getRow();
            int buttonCol = button.getCol();

            // TODO: 根据按钮的位置和当前玩家位置进行移动判断和更新逻辑的实现

            // 示例代码：点击格子后玩家向上移动一格
            if (buttonRow == playerRow - 1 && buttonCol == playerCol) {
                movePlayer(buttonRow, buttonCol);
            }
        }
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(() -> {
            PushBoxGame game = new PushBoxGame(5, 5);
            // TODO: 添加初始化地图和玩家的逻辑
            game.updateGridButton(2, 2, "P");
            game.updateGridButton(3, 2, "B");
            game.updateGridButton(4, 2, "T");
            game.playerRow = 2;
            game.playerCol = 2;
        });
    }
}

请注意，这只是一个简化的示例代码，您需要根据具体要求补充完整的游戏逻辑，包括移动箱子、判断是否完成目标等功能。希望对您有所帮助！
