For 2.1.1 take a look at the displayName methods in DisplayUtilities (http://openimaj.org/apidocs/org/openimaj/image/DisplayUtilities.html).
For 2.1.2, you can just use the different drawing methods to make something that looks nice (in particular drawShape/drawShapeFilled); there is no exact solution.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Do you guys have a solution for these Exercise?
