Hello All,
I did the test yesterday and unforutnately did not pass. Here is my section analysis

# Fundamental Object Oriented Concepts 75%
# UML Representation of Object Oriented Concepts 83%
# Java Implementation of Object Oriented Concepts 62%
# Algorithm Design and Implementation 50%
# Java Development fundamentals 33%
# Java Platform and Integration Technologies 40%
# Client Technologies 80%
# Server Technologies 42%

Server side technology was hard i thought.

i think the Java Development fundamentals was the code questions. like was is the output of this for loop.

Can anyone see what i could study for next thursday?

Also can i talk about the questions i got in the exam on the forum. i can remember a few of them word for word cause i kept thinking about them afterwards. i will post them up if i can.

thanks

We're so sorry to hear about your small margin of error. Don't despair. I mean, the odds are that with a different set of questions from the exam pool, you probably would have passed.

Ask all the questions you want in this forum, and we always love answering questions, but any questions posted directly from your exam need will end up getting deleted from this forum - we've got to respect the copyright Sun has on the exam, while at the same time, maintaining the integrity of the certification. If people posted the questions here 'word for word', we'd be doing ourselves, and every other Java professional, a disservice.

Having said that, please ask away with questions, topics, clarification and other things. There are alot of ways to learn about a subject or topic without posting an actual exam question. If there's a subject you're unclear about, please ask, and we'll all try our darndest to answer.

Don't give up. You're SO close!

Just got quick couple of question that clear my head for thursday exam.

Does J2EE always need J2SE on the serverSo if you are making a EE application you would need J2SE?

Can servlet interact with the database. I know they are not suppose to law but can they still?

Does a java applet need a jre or a JDK on the machine to run?

i will probably have more tomorrow if you do not mind. just studying all around.

Does J2EE always need J2SE on the serverSo if you are making a EE application you would need J2SE?


Yes. All of the APIs in the SE environment are available to a J2EE application. A J2EE application can call an EJB, but it can also call a java.util.List or a java.lang.String. So, the EE environment builds upon the J2SE environment. This cannot be said for micro devices. Micro devices do NOT have access to all of the J2SE class libraries.

Can servlet interact with the database. I know they are not suppose to law but can they still?


Absolutely! It's a simple JDBC call, and they can issue SQL statements. By the way, JDBC is part of J2SE, so this would be a solid example of a J2EE component leveraging its ability to use a J2SE API.


Does a java applet need a jre or a JDK on the machine to run?


In order to RUN a Java Applet, the client must have a JRE, Java Runtime Environment, installed on the client machine. The JRE comes with an applet viewer, as well as a variety of browser plugins.

i will probably have more tomorrow if you do not mind. just studying all around.


Ask, ask, ask! That's what we are here for!

thanks for the reply Cameron,

Can a abstract class extend another abstract class?

Why do you have to use d and f with float and double. does it make a difference if you do not use them?

thanks for the help

Indeed. And they often do. Try it out!

The compiler assumes any decimal is a double, so to tell the compiler that you're using a float, you throw the 'f' in there. I'm not sure if there is any time you MUST use the 'd'. To be honest, I didn't even know the 'd' option existed until I started doing certifications. But the 'f' options is needed when you are using floats.

Don't be afraid to start a new thread! This one is getting hijacked with great information on the SCJA exam.

Congratulations! I'm so happy for your success!

You know, sometimes you can really just get a tough set of questions from the exam pool. 78% is a great score on a tough exam. This exam covers more material than any other exam - even SCEA. It's not as deep, but it wide, and that makes it a real challenge.

Really, I never had any doubt.

Congratulations!!!
