[FIXED] Java: Have String Constant match its value

Issue

Is there an easy way in Java 8 to have String Constants match its value, instead of doing this repetitively?

public static final String PATIENTID = "PATIENTID";
public static final String CREATEDDATE = "CREATEDDATE";
public static final String PREFIX = "PREFIX";
public static final String FIRSTNAME = "FIRSTNAME";
public static final String MIDDLENAME = "MIDDLENAME";

Solution

You could use an enum:

public enum Field {
    PATIENTID,
    CREATEDDATE,
    PREFIX,
    FIRSTNAME,
    MIDDLENAME;
}

and when you want to use one of your strings, you can use for example Field.PATIENTID.name(), which will return the string "PATIENTID".
