Java 测试设置向导出现错误

我想制作一个安装向导，它将要求您输入寡妇的背景色。此外，我还需要一个浏览按钮，用于保存IconImage类型的变量。我得到了这段代码的编译错误。请帮忙！以下是开始代码：

欢迎任何帮助/新代码！ 谢谢

顺便说一句，JList可以由一组字符串组成。我不明白！请帮忙

我不认为

Color

是一个枚举；它有一堆静态变量，但没有定义为枚举

也就是说，给给定的类添加更多的值通常是个坏主意。最好的选择是实例化

Color

变量，然后将其指定为一种现有颜色或使用

Color（int r，int g，int b）

构造函数，如下所示：

Color purple = new Color((139, 0, 139);
guiObject.setBackground(purple);

---

如果您必须使用

颜色。//我的变量
格式，只需创建一个新类，比如
公共类CustomColor extends Color
，然后根据您的心意进行调整。

你可以试试这段代码，它会在每次单击“颜色”时侦听，并将颜色保存到“colorSelected”。您可能需要对它进行一些调整，因为它被调用了两次，因为单击是两个事件。无论如何，希望它能满足您的要求：

import javax.swing.*;
import javax.swing.event.ListSelectionEvent;
import javax.swing.event.ListSelectionListener;

public class Setup {

    private static String colorSelected;

    public static void main(String[] args) {
        JFrame f = new JFrame("Test Setup wizard");
        JLabel question1 = new JLabel("What would you like the background color to be?");
        final String Colors[] = new String[]{"black", "blue", "cyan", "darkGray", "gray", "green", "lightGray", "magenta", "orange", "pink", "red", "white", "yellow"};
        JList colors = new JList(Colors);
        colors.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
        colors.setLayoutOrientation(JList.VERTICAL);
        colors.setVisibleRowCount(-5);
        colors.addListSelectionListener(new ListSelectionListener() {
            public void valueChanged(ListSelectionEvent e) {
                int index = e.getFirstIndex();
                colorSelected = Colors[index];
                System.out.println(colorSelected);
            }
        });

        JScrollPane listScroller = new JScrollPane(colors);
        f.add(colors);
        f.setSize(500, 500);
        f.setVisible(true);
    }
}

此外，我认为大多数人都会混淆“Colors”是一个枚举，因为它是大写的。颜色只是一个字符串数组。惯例是使用camelCase对象名称，因此“colors”是一个更好的名称，您可能应该将JList“colors”重命名为“JList”
