•Split up classes with too much
responsibility
•Sometimes a top level
class ends up with far too many operations because all commands
are simply added to it
•Eliminate classes with too few
responsibilities
•A class with no
operations is not useful. What would you do with its objects?
•A class with only one
or two operations may be useful, but you should convince
yourself that there is really no better way of distributing the
responsibilities
•If another class can
meaningfully carry out the task – move the operations there and
eliminate the class
•Eliminate unused responsibilities
(operations)
•Reorganize unrelated
responsibilities – move it to a different class or add it to a new class
