There's nothing in the SDK named Rect
.
There is, of course, java.awt.Rectangle
, which may help you on your quest.
However, it looks like Rect
was just some other class in the project you grabbed that you forgot to grab the source for (or the author didn't make it available).
It wouldn't require a special import
or anything if it was in the same package as DrawRects
(the default package, by the looks of it) or if it was, say, an inner class of DrawRects
(which it's not).
