update lab task 5f in w01 to clarify type

[johannesnydahl]

To generalize kvadrat and stapel so that the pen and fill color can be specified, one needs to know the type of color variables in Kojo. For students to figure the type out, they either have to study the Kojo source code or use Metals' type derivation.

I think the type should be specified in this task to minimize confusion.

Good point! Is it java.awt.Color or some other Kojo-package with own Color? (I've forgot about this detail as it was a while ago I touched the Kojo internals...) I guess it would be good to state the full package path of the type if you want to take a look in the Kojo code and update your PR?

[bjornregnell]

I've just checked. It is java.awt.Color. Probably we should import it in the file where other stuff from kojo is imported...
EDIT: export not import

[johannesnydahl]

Yes. Should I still change PR even if we add export java.awt.Color to workspace file?

[bjornregnell]

Hmm. We have during the first week not mentioned import but the actual type is java.awt.Color so I suggest to update the PR with the last sentence being something like

Färgerna i Kojo är av typen \code{java.awt.Color}. 
Typen är tillgänglig under namnet Color då namnet är importerat med 
\code{import java.awt.Color}.

to avoid potential confusion.

PR is updated.

[bjornregnell]

I suggest that you change importerat med export till gjorts direkt tillgängligt med export

[bjornregnell]

Och jag tror det fattas ett "i" före "vecka 4"

[johannesnydahl]

My bad. Should probably be fixed now?
