It is more JSwing quiz then Java quiz.
I agree with your answers but I must admit that I'm not sure about 50% of
answers. I think quiz is hard and stupid and it is just answer to the
question : did you spend more than 5 hours working with JSwing every day in
the past three months?

I wholeheartedly agree with Mladen. Whoever designed this quiz has a
very narrow view on Java. If *I* had been told to write a Java quiz, I
would have focused on more language-level aspects instead of a
particular API.

I wholeheartedly agree with Mladen. Whoever designed this quiz has a
very narrow view on Java. If *I* had been told to write a Java quiz, I
would have focused on more language-level aspects instead of a
particular API.

I've been programming with Java since 96, first with CORBA for about 4
yrs and then J2EE for the last 3. I know bordering on nothing about
swing, but I can look up an API, which is all the above test requires.

General Java questions like...tell me about scope in Java? How would
one use notify()? What constructs in Java help me to write thread safe
code? Multi Threaded code? Tell me about Java's use of exceptions? How
would I right exception safe code? Tell me about how Java uses
interfaces?

what does answering a question like the following tell you about my
understanding of Java?
Which of the following is not a valid constructor for a JLabel?
a)JLabel( int, horizontalAlignment, Icon image ); b)JLabel(
Icon image );

Absolutley nothing. For a start lets say ( and I don't know if ..)
(b) is the "wrong" answer, big deal...as far as encapsulation goes
...it seems
reasonable to give a label object a c'tor with Image as an arg?
A better question would be.. examine the JLabel API and discuss its
encapsulation?

I have to say I agree with you as well. Learning Java is more... MUCH
more than memorising the JSwing API. You don't learn a foreign language
(for example German if you're English yourself) by reading through the
dictionary, memorising words alphabetically, do you?
Your example questions above are much better than those in the quoted
quiz, but the ones *I'd* ask would go into even more basic concepts of
the Java language.
