How to get an enum value from a string value in Java?

Say I have an enum which is just

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 . How would it be possible to do this?

Is the Enum.valueOf() the method I need? If so, how would I use this?

Yes, Blah.valueOf("A") will give you Blah.A .

Note that the name must be an exact match, including case: Blah.valueOf("a") and Blah.valueOf("A ") both throw an IllegalArgumentException .

The static methods valueOf() and values() are created at compile time and do not appear in source code. They do appear in Javadoc, though; for example, Dialog.ModalityType shows both methods.
