我正在上课的轮盘赌游戏，不知道出了什么问题。它会编译，但是当我运行它时，面板就不会显示出来。如果你们中的一个人可以查看我的代码，那就太好了。而且我知道我可以使用循环来做很多这样的事情但是现在我只是想让它运转起来。 感谢

在建立用户界面后，最后致电setVisible
public Layout(){
super(title);
// Use pack, it's safer, but do this JUST before you call setVisible...
setSize(size);
setResizable(false);
// Move me...
//setVisible(true);
setLocationRelativeTo(null);
setDefaultCloseOperation(EXIT_ON_CLOSE);
add(panel);
spin.addActionListener(this);
//...
panel.add(spin);
panel.add(empty);
panel.add(MoneyLabel);
// To here
setVisible(true);
}
