Hi all,

why is the option

An application can either use module-path or classpath but not both.

wrong?

Thank you in advance

It is wrong because you can use both the switches.

Hi admin,

This option states:

A module can be used by non-modular code by putting that module on the classpath.

Shouldn't it be "A module can be used by non-modular code by putting classes of that module on the classpath."

something like: java Main -classpath mymod/my.pack1.*;mymod/my.pack2

Please, help, I am confused I've already read about classpaths and modules. I can't understand why this option is correct!?

[admin]

Yes, that is what it means. You can also put the module jar on the classpath, instead of individual classes.

Hi, my understanding is,
The exports just exports, but not opens.(it is accessible but not reflectively.)
opens just opens, not exports.(it is only accessible reflectively.)

is this correct.

[admin]

Right. exports allows compile time dependency while opens allows runtime dependency through reflection.
