Am not an expert or anything so i may be wrong.

What is Display? .. maybe u forgot an import of some sort.
Also should probably look like :

I tend to belive that u may have forgotten some import cause repaint doesn't work as well... Maybe java.awt or java.avt.event .. I never worked in microjava so i'm just guessing

just my 2 penys
