\begin{itemize}
\item Realization arrow should have an outline triangle
\item UML diagram can also show interface method names
\item Realization arrow is like weak generalization (inheritance)
\item From last day, Baber focuses on translating low level mathematical
expressions
\item In our specification, we will also need to organize the information
\item For larger problems, think about your types, Abstract Data Types and
Abstract objects
\item Interactively switch between types, ADTs, Abstract Objects and detailed
mathematical spec

\item Methods are implicitly abstract and public

\item Cannot have constructors
\item Variables are final
\item Can only extend interfaces
\item Classes can extend multiple instances
\item Appropriate for unrelated classes
\ei
\item Abstract class
\bi
\item At least one method is declared as abstract
\item Some methods can implement a default behaviour
\item Cannot instantiate them, but can have constructors
\item Variables are not necessarily final
\item Can extend other class
\item Can implement multiple interfaces
\item Classes can extend only one abstract class
\item Sharing code between closely related classes
