Question

I have a really strange enum bug in Java.

for(Answer ans : assessmentResult.getAnswersAsList()) { //originally stored in a table     //AnswerStatus stat = ans.getStatus();     if (ans.getStatus() == AnswerStatus.NOT_ASSESSED) {         assessed = false;     } } 

An answer is an answer to a question on a test. An assessment result is the result a student gets on a test (this includes a collection of answers).

I’ve debugged the above code, and ans.getStatus() returns AnswerStatus.ASSESSED. Still, the if line returns true, and assessed is set to false.

But, the thing I think is most strange; When I declare the AnswerStatus stat variable, it works, even if I don’t use the stat variable in the if test. Could someone tell me what is going on?.

I’ve read something about enum bugs in serialization/RMI-IIOP but I don’t use that here. The enum AnswerStatus can be ASSESSED or NOT_ASSESSED.

The getStatus method in class Answer just returns the status, nothing else.

Answer 1

Solved.

It was the NetBeans debugger that tricked me. It does not pass the if test (although NetBeans says that).

Sorry for the inconvenience 🙂
