Query on exam objective 1Z0-803

[Prathima gaitonde]

Hi All,

1> Is "Enums" there on IZ0-803 Exam? K&B book, covers it in first chapter itself. They have asked few questions in the selftest part, on the topic.
This link does not mention the topic in the exam objective!!!

2> I referred Mala Gupta and K&B books for preparation of the exam, and also attempt few questions from Enthuware software. System.arraycopy(), is not mentioned anywhere in these 2 books, but according to Enthuware software its there on the exam. How many such topics are there on the exam which are not covered by these 2 books? Can any of the pupil who have attempted the exam guide me please!

Thanks,

Kind regards,
Prathima

What kind of questions did you get from wrapper? Which area from wrapper class should I study more?
I do know very little about wrapper, such as equals() methods, assignment values (which can fit, which can not compile etc.).

Please guide me.

Thanks,

With kind regards,
Prathima

if you try entuware and understand all question about wrappers from it you will be good.
This was my preparation topics:
1. Creation: Boxing / Unboxing, by methods of wrappers class
2. Manipulations (arithmetical operators), Boxing / Unboxing
3. Passing to method.
3.1. Chose of overloaded method when pass primitive or wrapper.
4. Immutable of wrappers and also in context of previous 2 topic
5. Testing equality with equals method and ==
6. default value of instance and static variable and in context of 2 and 3

I took the OCAJP7 yesterday. I didn't encounter any question on enums. For the OCAJP7 you definitely don't need to know enums as it's not mentioned in the Exam Topics (as you mentioned). But as you know (or should know) Oracle can change these objectives at any given point. So it could become an exam topic in the (near) future.
The only thing you must know: enum is a keyword, so it's illegal to use it as a name for an identifier (as Java is case-sensitive eNum and Enum are allowed )

Both books offer a very good coverage of all exam topics. But as already mentioned Oracle can change the exam topics whenever they want. But updating a book takes much longer than updating a software product. Enthuware does a great job incorporating comments made by their users who took the exam. So if anyone mentions getting a question about wrappers, then Enthuware will add a few questions on wrappers so you are fully prepared.

On the exam I definitely had a few questions about wrappers. I can't discuss/mention any details, because that's against Oracle's policy. No question about System.arraycopy() at all. The list with preparation topics of Sergej is more than enough to answer all questions on wrapper classes correctly.

Hope it helps!
Kind regards,

Hi Sergej & Roel,

Have you encountered questions on "multi catch clause"?

Something like this:

catch(ClassCastException | ArithmeticException e)
{
//do something!!!

}

With great respect,
Prathima

The multi-catch exception handling is NOT a topic for OCAJP7 but it is for OCPJP7.
