Goals:

• have a simple yet satisfying design experience.
• be more comfortable defining procedures that describe simple computations.
• know how to define a class and instantiate it as an object.
• know how to declare and access instance variables within a class definition.
• be able to define constructors, accessors, and other methods.
• know how to invoke methods on an object.
• know how to create a new object inside a method and return it as the result of that method.
• know how to call methods of one object from within another object.
• have some familiarity with displaying simple graphics shapes using the CS101Canvas.

The design is an exercise to be turned in by 2 PM on the Design Due Date shown above. In class on that day, a sample design will be presented.

In Lab, your graded design will be returned. You may then proceed with your own design or adopt the presented design for your implementation.
