为 Java 中的类项目构建一个简单的 Rock Paper Scissors GUI 游戏。

尝试使用 MVC 方法，我将resultsGUI()下面的代码从“控制器”类移到“视图”类。

我尝试在 Controller 类中创建 View 类的实例并像这样调用该方法：view.resultsGUI();但这在我的编译器中引发了异常错误。

如何调用resultsGUI驻留在我的 View 类中的方法以在方法的底部chooseWinner()（也在下面）执行，就像代码在它的一部分时所做的那样chooseWinner()？

我是新手，感谢您的帮助。

selectWinner 方法如下：

    public static void chooseWinner(int x) {
    playerChoice = x;

    String winningCombo = "" + Math.min(compChoice, playerChoice)
            + Math.max(compChoice, playerChoice);

    switch (Integer.parseInt(winningCombo)) {
        case 1:
            text = "Paper wins!";
            if (playerChoice == 2) {
                playerWon = 1;
            }
            break;
        case 2:
            text = "Rock wins!";
            if (playerChoice == 1) {
                playerWon = 1;
            }
            break;
        case 3:
            text = "Scissors wins!";
            if (playerChoice == 3) {
                playerWon = 1;
            }
            break;

    }

    if (playerWon == 1) {
        text1 = "Congrats, you win!";
        playerWon = 0;
        win = win + 1;
        total = total + 1;
    } else if (playerWon == 2) {
        text1 = "It's a tie!";
        playerWon = 0;
    } else {
        text1 = "Computer wins!";
        total = total + 1;
    }




}

resultsGUI 方法如下： public void resultsGUI() { JFrame rFrame = new JFrame("Match Results"); 容器面板 = rFrame.getContentPane(); panel.setLayout(null);

    JLabel l0 = new JLabel(controller.text1 + controller.text);
    l0.setBounds(75, 10, 300, 35);
    panel.add(l0);


    //show the result in a new splash screen

    JLabel l1 = new JLabel("Human's Choice");
    l1.setBounds(40, 35, 150, 35);
    panel.add(l1);

    JLabel l2 = new JLabel("Computer's Choice");
    l2.setBounds(215, 35, 150, 35);
    panel.add(l2);

    JLabel l3 = new JLabel(new ImageIcon(System.getProperty("user.dir") + "/image/" + (controller.playerChoice - 1) + ".jpg"));
    l3.setBounds(10, 100, 170, 60);
    panel.add(l3);

    JLabel l4 = new JLabel(new ImageIcon(System.getProperty("user.dir") + "/image/" + (controller.compChoice - 1) + ".jpg"));
    l4.setBounds(200, 100, 170, 60);
    panel.add(l4);

    JLabel l5 = new JLabel("Win/Loss rate: " + controller.win + "/" + controller.total);
    l5.setBounds(125, 25, 150, 350);
    panel.add(l5);

    JLabel l6 = new JLabel("Tie: " + controller.tie);
    l6.setBounds(125, 30, 125, 370);
    panel.add(l6);

    rFrame.setSize(400, 270);
    rFrame.setVisible(true);
}

你的控件应该有一个视图和模型的实例，而不仅仅是任何视图和模型实例，而是活动的当前可视化视图和当前使用的模型。像这样的东西可能在你的类中使用 main 方法：

public static void main(String[] args) {
  View view = new View();
  Model model = new Model();
  Control control = new Control(view, model);

  // start the GUI up
}

在您的 Control 类中，您将使用构造函数参数来设置类字段：

public class Control {
  private View view;
  private Model model;

  public Control(View view, Model model) {
    this.view = view;
    this.model = model;
  }

  // now your control can call model and view methods.
  // ....
}

您需要Game与其他课程组成您的课程。所以你得到这个： 

class Game  
{     
    View view = new View();  
    public void foo()  
    {  
        view.getResults();
    }    
}

如果您不想实例化View该类，可以将getResults函数标记为静态并像这样引用它： 

View.getResults()
