About Question enthuware.ocpjp.ii.v11.2.3430 :

1. Convert ojdbc8.jar into automatic module.
2. Convert analytics.jar into a named module by adding module-info.java to it.
In this module-info, export all packages that are used by reports.jar and add requires clauses for all packages of ojdbc.jar that are used by analytics.jar.
3. Convert reports.jar into a named module. Add requires clause for analytics module in reports's module-info.java.

This option is not correct because it converts analytics.jar into named module. Am I correct?

[admin]

Yes, as explained in option 2. Added explanation to this option as well.
thank you for your feedback!

I almost guessed wrong, because you state "module-info.java", where it could (or should) be "module-info.class".

[admin]

The problem statement clearly asks you the steps that will be required to modularize your application. How will you add a requires clause to module-info.class unless you write it in module-info.java?

[AlienFS]

I totally understand what you are saying and I did clearly read that myself. The answers however don't clearly state you need to write a source file and add the compiled file to the .jar.

When you write in answers:
- 1: "reports.jar in its module-info.java"
- 2: "module-info.java to these jars."
- 3: "in reports.jar in its module-info.java"
- 4: "analytics.jar into a named module by adding module-info.java to it"

I cannot help but consider it a trick question as:
- 1: will not work, that file is not present in the .jar. It's will be present in the source folder, but not in the .jar.
- 2: will not work, needs to be .class for the desired effect.
- 3: will not work, that file is not present in the .jar.
- 4: will not work, needs to be .class for the desired effect.

The question doesn't state you need to recompile everything in your approach and it *could* be done simply by adding a module-info.class to the existing .jar. The answers, to me, hint to the latter approach.

In short: conceptually I totally knew what to do, but none of the answers make sense to me because of the .java extension.

[admin]

OK, I see your point. May be just "module-info" would be better?

[AlienFS]

That would certainly improve the situation.
