Convert a String to an enum 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.
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.

Another solution if the text is not the same to the enumeration value:
public enum Blah {
A("text1"),
B("text2"),
C("text3"),
D("text4");
private String text;
Blah(String text) {
this.text = text;
}
public String getText() {
return this.text;
}
public static Blah fromString(String text) {
if (text != null) {
for (Blah b : Blah.values()) {
if (text.equalsIgnoreCase(b.text)) {
return b;
}
}
}
return null;
}
}
