录制用户选择java

我有一个滚动框，用户可以在其中选择选项。如果我想让用户选择在其他地方打印，我需要调用什么？我已经有了我想要的用户选择

 results.setText();

对于（int i=1；i首先，您在代码中犯下的所有错误：

您正在将
JComboBox ageEntries；
和
JComboBox raceList；
声明为您的实例变量和init（…）方法中的本地变量。不要声明它们两次，只使用实例变量或本地变量（视需要而定），但不要使用它们两次
始终将添加此ilne
frame.setDefaultCloseOperation（JFrame.EXIT_ON_CLOSE）；
作为JFrame的对象，这有助于以良好的方式关闭JFrame窗口
现在了解如何在
results.setText（）；
中编写。您可以在容器类中创建一个验证方法，该方法将返回
boolean
，并将在
actionPerformed（…）中调用
下一个按钮的方法

并在该方法中检查用户输入的值是否合法，如果它们是合法值，则使用

StringBuilder

将其附加，如

StringBuilder sb = new StringBuilder(); // this will be your instance variable not local.
sb.append((String) ageEntries.getSelectedItem());
sb.append(" ");  // Add this space to distinguish between two values.
// and so on for other values.

---

完成后，您可以编写

results.setText（containerObject.sb.toString（））；

来显示这些值。

这是非常模糊的。您能添加更多的细节而不是询问括号中应该包含什么吗？例如，

结果的类型是什么？

？结果的类型是JTextField，我希望用户在其中选择。用户可用的选项是组合框中的字符串和int或您想要的复选框要将用户从复选框或组合框中选择的内容打印到名为

results

的

JTextField

组件中，我想我们需要能够看到其余的代码，以便能够帮助您完成这项工作。请学习java命名约定并遵守这些约定。感谢您的建议。我正在尽最大努力学习这门语言。这是我的第一个项目，我已经学到了很多。
