如何从Java中的字符串值获取枚举值？ - How to get an enum value from a string value in Java?

问题：

Say I have an enum which is just 说我有一个枚举

public enum Blah {
    A, B, C, D
}

and I would like to find the enum value of a string, for example "A" which would be Blah.A . 我想找到一个字符串的枚举值，例如"A"就是Blah.A How would it be possible to do this? 怎么可能作到这一点？

Is the Enum.valueOf() the method I need? Enum.valueOf()是我须要的方法吗？ If so, how would I use this? 若是是这样，我将如何使用它？
