Hi Sarim,
Please find replies mentioned against each of your queries mentioned below:
1. applets
2. applet tags
[Answer]We do not find these terms explicitly mentioned in the exam objectives but it is better to be aware of the basics. Suggest you to go through Pages.16-18 from the book "A programmer's guide to Java Certification" authored by Khalid A.Mughal and Rolf W.Rasmussen, Addison-Wesley for discussion on main elements of an applet. Pages.488-490 [Sections 16.1-16.2],
Pages.493-496 of the same book discussing further details about applet life cycle is also advisable.
3. command line codes besides javac and java, dealing with jar files
[Answer]Again, this does not find a mention in the exam objectives, but if you feel that it might be prudent to know the command line options, just type jar with an empty parameter on the command line and take a look at the options once or twice.
4. listener attributes from Java 1.0.2 where if a listener returns false events are passed up the heirarcy (do we need to know how this works ?
[Answer]Just read once and try to see the difference between the event delegation models. We cannot rule out the possibility of a question on this but not knowing about it may not hinder the chances of success in the exam either.
5. methods of collection interface and classes, do we really need to know a lot of these and how they work, since i have never really come across questions dealing with them and there seem to be quite a lot !
[Answer]Believe me, this was quite baffling to me also on the first round of study, but once you study the topic 2-3 times, you will learn to appreciate the common characteristics of all the classes in the Collections Framework, knowing common methods in the Collections Framework can help you a lot. Try going through the tutorial on Collections Framework at:
