Enum for key name and value

Question

I want to use Enum as a key value. I tired this:

public interface ElementTypeEnum
{
    public static String QUEUE_TRANSACTION = "queue_transaction";

    public static String QUEUE_API_ATTEMPT = "queue_api_attempt";
}

but when I tried to use it this way: QUEUE_TRANSACTIONs cannot be resolved or is not a field

What is the proper way to use it?

How and where did you try to use it? Also notice that `QUEUE_TRANSACTIONs`, has an extra `s` — ernest_k, Jun 13 '18 at 09:54
Where is the enum you are talking about? This is currently an Interface with two static fields. — Ben, Jun 13 '18 at 09:55
`enum` with `private string key` can actually help you to enclose more details. — Hearen, Jun 13 '18 at 09:55
also declaring constants in an interface is a common anti-pattern — Eugene, Jun 13 '18 at 09:58

Enum and interface are two different concepts in general, so you need to read :

https://docs.oracle.com/javase/tutorial/java/concepts/interface.html

What are enums and why are they useful?

https://docs.oracle.com/javase/tutorial/java/javaOO/enum.html

What is the use of interface constants?
