来自字符串“Yellow”的 Java 颜色
有什么方法可以从字符串中获取颜色（例如“白色”）？
Color color;
Field field = Class.forName("java.awt.Color").getField("Yellow");
color = (Color)field.get(null);
我尝试 在 Java 中将字符串转换为颜色 并抛出 error 。 “领域”属于什么？我需要导入什么包？
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);
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?

这是因为定义黄色的字段被命名为
YELLOW或yellow您有一个大写的 Y，它无法映射到颜色。相反，请尝试：
查看此类以获取 Color 中包含的所有字段
http://download.oracle.com/javase/6 /docs/api/java/awt/Color.html
代码只是使用反射来访问这些字段之一。
然而，颜色列表非常有限，所以我不知道这对您来说有多大用处。
It is because the field that defines yellow is named
YELLOWoryellowYou have an uppercase Y, which cannot be mapped to a Color. Instead, try:
Look at this class for all the fields contained within Color
http://download.oracle.com/javase/6/docs/api/java/awt/Color.html
The code is just using reflection to access one of these fields.
The list of colours however is quite limited, so I don't know how much use this is likely to be for you.
“黄”不是“黄”
"yellow" not "Yellow"
