Lookup enum by string value

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?

Answer

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

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.
