Hi guys!

Unfortunatelly i can check it, so i try to ask you .

Woud it be a compile error if  in modules A,B,C    B is requires transitive A  since  C requires A and B ?

The question is: Does java allow  make explicitly call  requires by module when it's module will come transitivily?

Thank you!

I believe an extra requires (while a module already transitively required) will not cause compilation error.

If A requires B and B requires C, that doesn't necessarily mean A requires C. In the context of modules, "requires" essentially means there is a compilation dependency.
You need A "to require" C (i.e. A needs to have a requires clause for C) only if A accesses classes in C.

Then there is requires transitive.

Strongly suggest you to try the modules stuff out on your machine. It is almost impossible to remember the commands, switches, module info, and directory structure, without actually doing this stuff manually, and you will need to know all that the exam.
It does feel a little overwhelming at first but gets easier after you write and compile a simple test module once.

Thank you for answers.

I also interested in  taking exam from home.

But i don't find any information  about using a paper.
In requirements ask to keep you desktop clean without any paper.

So it looks like disadvantage of taking exam from home ..

Am i right? Or i miss something ?


I found the answer :
Some exam programs allow you to use a built-in digital whiteboard during your OnVUE exam. You can use the digital whiteboard to do scratch work or take notes. Physical scratch paper or note boards are not allowed when taking an OnVUE exam.

During your exam, you are not allowed to use exam-specific materials and you are not permitted to use any physical writing instruments such as a pen, marker, or pencil.


There is an example of whiteboard for training   https://home.pearsonvue.com/onvue/whiteboard
