我正在用Java创建一个三卡扑克游戏。 我现在基本上完成了编码，但是我遇到了GUI的一些问题。 这是我的图形部分代码：

主要的问题是在createAndShowGUI()中，如果我把那个while循环，我试过（for循环，做循环）那里，JPanel只会出现但没有任何内容。如果那里没有while循环，JPanel会定期显示其中的所有内容。
但是我需要while循环中的代码，因为代码基本上就是游戏。
我尝试创建自己的方法（play()），但如果我在main()或其他地方调用它，则JPanel将为白色（无）。
这是我的第二个问题：如果你删除while循环并且JPanel正常显示，你会看到计算机的手和玩家的手，但是以文本形式。我想知道如何用图像替换文本。
答案 0 :(得分：1)
很少有东西，并非所有东西都与GUI直接相关：
丢失静态成员，它们不应该存在，我假设您使用它们，因为从main方法调用了所有内容，但这不是可行的方法。 Java是一种面向对象的编程语言，创建类，实例化它们并使用它们，不在一个类中执行所有工作，甚至没有实例化。
重构代码，而不是创建具有一个值差异的不同类，创建更多泛型类。例如，而不是像这样的5个不同的类：
static class ten implements ActionListener{
public void actionPerformed(ActionEvent e){
if(playermoney<10)
wlt=9;
else
bet=10;
}
}
声明一个这样的类：
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;
}
}
并根据具体情况使用适当的int对其进行实例化。
让应用程序成为事件驱动。由于玩家必须互动，不要使用大的循环，而是从听众触发事件（例如现在发生的情况）（即用户按下按钮）
与前一点相关，不要在UI线程上执行长动作（如整个程序），不会让UI更新，在后台线程上执行所有工作，以及何时需要更改用户界面，使用SwingUtilities.invokeLater(Runnable)。我想你可能会发现this tutorial有帮助。
答案 1 :(得分：0)
对于GUI，您应该实施Runnable并使用SwingUtilities.invokeLater(Runnable)：
public class Foo implements Runnable {
public static void main(String[] args) {
SwingUtilities.invokeLater(new Foo());
}
public void run() {
...
}
}
要使用图像，您应该使用ImageIcon类：
ImageIcon imageIcon = new ImageIcon("<path to image>");
或者如果您已经有Image个对象：
ImageIcon imageIcon = new ImageIcon(image);
然后显示它：
JLabel imageLabel = new JLabel(imageIcon);
