需要關於java的幫助GUI

我正在用Java創建一個三卡撲克遊戲。我基本上已經完成了編碼工作，但是我遇到了一些GUI問題。這裏是我的顯卡部分代碼：需要關於java的幫助GUI

     setmoney(); 
     javax.swing.SwingUtilities.invokeLater(new Runnable() { 
      public void run() { 
       while(compmoney>=10&&playermoney>=10) 
       createAndShowGUI(); 
       if(playermoney > compmoney) 
        wlt=5; 
       else 
        wlt=6; 
      } 
     }); 
    } 
}

的主要問題是，在createAndShowGUI()，如果我把while循環，這是我試過（for循環，do循環）那裏，JPanel將剛剛出現，但沒有在那裏。如果在那裏沒有while循環，那麼JPanel將定期顯示在那裏的所有東西。但我需要while循環內的代碼，因爲代碼基本上是遊戲。

我試圖做一個自己的方法（play()），但如果我在main()或任何地方調用它，JPanel將是白色（無）。

這是我的第二個問題：如果刪除while循環並且JPanel正常顯示，您將看到計算機的手和玩家的手，但是是以文本形式。我想知道如何用圖像替換文字。

您不希望事件驅動程序中出現繁忙循環。 – sje397 2011-05-19 03:54:05

重寫代碼並擺脫所有靜態變量和方法。 Thast不是設計程序的方式。 – camickr 2011-05-19 04:26:47

而且，請遵循通常的Java命名約定，以便爲類名使用！沒有Java程序員會想要在當前狀態下檢查你的代碼。 – jfpoilpret 2011-05-19 06:59:02

對於GUI，你應該實現Runnable，並使用SwingUtilities.invokeLater(Runnable)：

public class Foo implements Runnable { 
    public static void main(String[] args) { 
     SwingUtilities.invokeLater(new Foo()); 
    } 

    public void run() { 
     ... 
    } 
}

爲了使用圖像，您應該使用ImageIcon類：

ImageIcon imageIcon = new ImageIcon("<path to image>");

或者相反，如果你已經有一個Image物件：

ImageIcon imageIcon = new ImageIcon(image);

然後顯示它：

JLabel imageLabel = new JLabel(imageIcon);

有幾件事情，並不是所有的人都直接GUI相關：

失去靜態成員，他們不應該在那裏，我假設你使用它們，因爲一切從主要方法調用，但這不是要走的路。 Java是一種面向對象的編程語言，創建類，實例化和使用它們，不要在一個類中執行所有的工作，甚至沒有實例化。

重構重複代碼，而不是創建不同的類與一個值的差異，創建更多的泛型類。例如，而不是5不同類這樣的：

static class ten implements ActionListener{ 
    public void actionPerformed(ActionEvent e){ 
     if(playermoney<10) 
      wlt=9;   
     else 
      bet=10; 
    } 
}

聲明一類這樣的：

static class ten implements ActionListener{ 
    int money; 
    public ten(int money) { 
     this.money = money 
    } 
    public void actionPerformed(ActionEvent e){ 
     if(playermoney<money) 
      wlt=9;   
     else 
      bet=money; 
    } 
}

，並根據情況用適當int實例化。

讓應用程序事件驅動。由於玩家必須進行交互，因此不要使用較大的while循環，而是從聽衆觸發事件（例如，現在發生什麼事情）。用戶按下一個按鈕）

與上一點相關，不要在UI線程上執行很長的操作（如整個程序），它不會讓UI更新，在後臺線程上執行所有工作，並且當您需要更改UI時，請使用SwingUtilities.invokeLater(Runnable)。我想你可能會發現this tutorial有幫助。
