如何從Java中的字符串值獲取枚舉值？ - How to get an enum value from a string value in Java?

問題：

Say I have an enum which is just 說我有一個枚舉

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 . 我想找到一個字符串的枚舉值，例如"A"就是Blah.A How would it be possible to do this? 怎麼可能作到這一點？

Is the Enum.valueOf() the method I need? Enum.valueOf()是我須要的方法嗎？ If so, how would I use this? 若是是這樣，我將如何使用它？
