Jshell questions

[germano.carella at gmail.com]

Hi to all,
I’m Germano from Italy.
I’m new of this list and java in general.
Perhaps these question are been asked, but I’m new and I don’t know differences between java 9 an java 8, so let me ask again.
1) I installed jdk-9 142 for Windows and I started using jshell.
I notice that jshell shows me sun.* classes but it won’t let me import them in any way. This is normal?
I read more java samples that use sun classes but I can’t try them.
2) In java 9 there are jmods files, I read, that I can use.
There is a way to use jmods with jshell? I can’t find documentation on how to make it easy; can you provide me some example?
Thanks for the moment!
Germano
