我对球员的顺序有疑问。我需要第一个玩家成为本轮的获胜者。所以我有，四个按钮，有可能阻止错误玩家的移动，比如“轮到你了，玩家二是第一个，因为是上一轮的赢家”

我怎么能控制它？最终验证的方法

我有四个卡片标签，每个玩家手上有五张卡片

对于每个按钮，设置我做的对应卡

//PLAYER1
    //card1 
    ActionListener one = new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            if (gr.getCounter1() < 5) {
                gr.setCounter1(gr.getCounter1() + 1);
                test1.setIcon(play1a);
                pn1.setText(Integer.toString(play2a));
                pn5.setText(play3a);
                pn50.setText(play4a);
            } else {
                pn5.setText("No more cards");
            }
        }
    };

    arraybtn[1].addActionListener(one);
    arraybtn[1].setPreferredSize(new Dimension(120, 20));

    play1a = gr.GameRules1().getImage(); //image of card
    play2a = gr.GameRules2(); // value
    play3a = gr.GameRules3(); // king of hearts for exemple
    play4a = gr.GameRules4(); // hearts

    arraybtn[1].setText(gr.GameRules3()); // button name

执行操作时：

if (whatever.getTurn() != thisPlayer) 
  error
else
  run normally

很简单。

你的程序有多少个课程？希望它有一个驱动 GUI 的非 GUI 模型，并且应该是这个完全相同的模型来决定游戏的控制。我不会像此线程中的一位海报所建议的那样抛出错误，而是使用游戏控制器模型只允许正确的玩家玩。GUI 将通过禁用所有不应按下的按钮并仅启用应按下的按钮来反映这一点。这如何在代码中实现取决于您当前程序的代码和整体结构。

编辑：除了回答

不确定你是否还在，但这里有一个快速拼凑的例子来说明我的意思。GamePlayer 类（显然）代表游戏的玩家，并且有一个字段 myTurn，仅当轮到该玩家时才为真，并且该字段具有关联的 void setMyTurn(boolean) 方法和 boolean isMyTurn() 方法。

GameModel 类有一个名为 player 的 GamePlayer 数组，一个 getPlayer(int) 方法，允许其他类获取数组中的每个 Player，一个 playerTurnIndex 表示当前轮到的玩家的数组中的索引，以及一个 advancePlay( ) 方法，该方法会增加此索引（根据玩家数组的长度进行修改，使其环绕），然后循环遍历玩家数组，根据 playerTurnIndex 值为每个玩家设置 myTurn 字段。

GameGui 类有一个名为 gameModel 的 GameModel 字段，并拥有一个 JButton 集合（实际上是一个 HashMap），并且在每个按钮的 ActionPerformed 方法中，调用了模型的 AdvancePlay() 方法，并调用了一个名为 enablePlayerTurns() 的私有方法来启用或禁用播放器 JButtons 取决于模型中对应播放器的值：

import java.awt.BorderLayout;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.HashMap;
import java.util.Map;

import javax.swing.*;

public class GamePlayMain {
    private static void createAndShowUI() {
        String[] players = {"John", "Bill", "Frank", "Henry"};
        GameModel model = new GameModel(players);
        GameGui gui = new GameGui(model);

        JFrame frame = new JFrame("GamePlayMain");
        frame.getContentPane().add(gui);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                createAndShowUI();
            }
        });
    }
}

        players = new GamePlayer[playerNames.length];
        for (int i = 0; i < playerNames.length; i++) {
            players[i] = new GamePlayer(playerNames[i]);
        }
        players[0].setMyTurn(true);
    }

    public int getPlayerTurnIndex() {
        return playerTurnIndex;
    }

    public GamePlayer getCurrentPlayer() {
        return players[playerTurnIndex];
    }

    public String[] getPlayerNames() {
        return playerNames;
    }

    public void advancePlay() {
        playerTurnIndex++;
        playerTurnIndex %= players.length;
        for (GamePlayer player : players) {

                player.setMyTurn(true);
            }
        }
    }

    public int getPlayerCount() {
        return players.length;
    }

    public GamePlayer getPlayer(int i) {
        return players[i];
    }
