The title is pretty self-explanatory. Here's my code so far:
public List<String> getVoucherStatuses() {
List<String> listOfStatuses = new ArrayList<String>();
for (VoucherStatus status : VoucherStatus.values()) {
listOfStatuses.add(status.name());
}
return listOfStatuses;
}
and here is the Enum:
public enum VoucherStatus {
GENERATED, INVALID, ISSUED, REDEEMED, EXPIRED
}
I keep getting null reference expcetion. What am I doing wrong? Thanks
If you're calling this from within the static initialiser of the enum, it wont have finished initialising which may well give you an NPE.
One work around is to use a nested class for the static.
