Convert a String to an enum in Java

Samuel Fernandes204208-May-2015
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.

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.  

You can use Enum.valueOf(Blah.class, string) as well.  

If you don't want to write your own utility use Google's guava library:
Enums.getIfPresent(Blah.class, "A")
