The Sudoku application is an implementation of the annotation method for the aspect-oriented (GoF) commands, and it is in essence a backtracking sudoku solver.

More exactly, this method implies the treation of a proxy class (as provided by Java's reflection package) together with an annotated interface which indicates the appropriate "undo" for each method. This allows a class' code to remain direct and uncluttered; the actions are generated at runtime and stored or undone by external handlers.

The problem is how to both use the command design pattern and retain the cohesion of directly implemented code. The command pattern promotes a method call to an object, improving program flexibility. The cost is source cohesion; either command code is injected into class, or the class' behavior is extracted into command subclasses.
