Congratulations!

Answers: A, A, B, A, B, C, A, B, A, B

The quiz was a little bit tricky! For example, "HyperlinkProvider" has nothing to do with the Output window. That's the factory class used for creating hyperlinks in the editor. Instead, the "OutputListener" is the class providing hyperlinks in the Output window. Another tricky question was the one about storing settings on disk. Sure, you'd use "SystemOptions", if you were using a pretty old version of the NetBeans Platform. However, since NetBeans Platform 6.0, you need the "NbPreferences" class instead. It's easy to use and it extends the JDK's own Preferences class (only difference is that the preferences are stored in the user directory, which is pretty handy). Another question that was a bit contentious was question 9 (after all, "XMLDataObject" is also for processing XML files, so either that or "XMLUtil" could have been a correct answer).

Those on the NetBeans Platform Students alias (i.e., anyone who has taken the NetBeans Platform Certified Training has access to this alias), will receive the next quiz in the next few days.

Hi Geertjan,
juhuu, I have won :) Question 4 is really tricky... Especially if you consider this Link: http://bits.netbeans.org/dev/javadoc/org-openide-options/org/openide/options/doc-files/api.html#intro
I'm really looking forward to receiving the shirt ;-)!
I think the quiz a good idea because it always refresh a little bit my NetBeans skills! Good job, thanks :) !!!
