我正在尝试让我的代码正常工作,以便当您按下“Go!”时 按钮,它要么抽一手牌,要么洗牌,具体取决于选中的复选框。我想我以后可以弄清楚,但现在的问题是当我按下“Go!”时 按钮,没有任何反应;它不使用 g.drawString() 绘制框或写入。

代码按顺序发生,这意味着您会看到一个文本框字段和一个按钮,按下该按钮会清除屏幕,然后显示“开始!” 按钮和复选框。但是当 go 被推动时什么也没有发生。

感谢您提供的任何帮助,非常感谢,这是代码(在其所有凌乱,未完成的荣耀中):

你还没有ActionListenergo按钮上附加任何东西......

尝试添加go.addActionListener(this);nameOk.addActionListener(this);
