Then put it on a site like Github or Pastebin and put a link in your message.

Then create a small sample that illustrates the problem.

A minimal-complete-example is not a dump of everything you have. It is creating a focused question. In fact, just the act of creating it can help you understand the problem.

Actually what makes me confuse, when I run the same query in Protege(with
all Qs,Ans/Options), it works and order the questions.
In Jena, the order by part does not work.

Sample data is not an abstract description of the data...it is proper
instance data, in best case in TURTLE syntax.

Sample code is still missing.

Sample output is not telling me that something does not work as expected...

"Not in the oder you want" is no real specification. The query will
order by the URIs of the complexity values. If not it's a bug.

But again, we need sample data, sample, code, which is also know as MWE.
And also the Jena version is interesting for the developers.

SELECT *
WHERE { ?questions dd:hasCategory dd:CatPhysics ; dd:hasLevel dd:levEasy
;
dd:hasComplexity ?y} order by ?y

Lorenz, Each question has three categories (subjects), has level , and
recently I added hasComplexity which has values 1-5. I have added a
Complexity class and its members are 1-5 numbers. Domain is Question
class
and range is Complexity class.
The query inside Jena works, load questions/answers/choices etc but not
in
the order I want.

That doesn't answer my question. Can you try to compare the same queries
please?

Moreover what's missing:

1. sample code
2. sample data
3. sample output

The queries are different because in Protege I retrieve only questions
and
their complexity number while in Jena I get questions, answers,
choices,
scores and its complexity order.

Thank you Lorenz, 1,2,3,4,5 are resources and it has URIs. Question

object property and value will be selected from one of the five values

"object property hasComplexity (its values are 1,2,3,4,5)"

-> why do you say it's an object property if the values are
numerical?


Moreover, you compare two different queries and then say one works in
Protege, the other not. That is a totally useless statement. It
should
be clear that you should compare the SAME queries


It remains open what kind of RDF term the complexity values
are...literals or resources

(The

still get data but not in order).
While this works inside Protege and show questions in order:
SELECT *
WHERE { ?questions dd:hasCategory dd:CatPhysics ; dd:hasLevel

dd:hasComplexity ?y} order by ?y
