Java的颜色从字符串＆QUOT;黄色＆QUOT; [英] Java Color from String "Yellow"

问题描述

有什么办法，我们可以从字符串得到的颜色（如白）？

Is there any way we can get color from String (like "White")?

Color color;
Field field = Class.forName("java.awt.Color").getField("Yellow");
color = (Color)field.get(null);

我试过在Java中并成为一个字符串转换为彩色抛出错误。
什么场是属于？我需要什么包导入呢？

I tried Converting a String to Color in Java and it throws error . What "Field" belongs to? What package do I need to import for it?

推荐答案

这是因为定义黄色的领域被命名为黄或黄

It is because the field that defines yellow is named YELLOW or yellow

您有一个大写Y，不能被映射到一个颜色。相反，尝试：

You have an uppercase Y, which cannot be mapped to a Color. Instead, try:

Field field = Class.forName("java.awt.Color").getField("yellow");

看这个类包含的颜色的所有字段

在code只是使用反射来访问这些领域之一。

The code is just using reflection to access one of these fields.

颜色列表但是是相当有限的，所以我不知道有多少使用这很可能是你。

The list of colours however is quite limited, so I don't know how much use this is likely to be for you.
