Document Summary

Object-oriented design-a problem-solving methodology that produces a solution to a problem in terms of self-contained entities called objects. Breaks up problems into collaborating objects (top-down breaks into tasks) Problems are solved by isolating the object: abstract the object with like properties and actions into groups(class, determining the responsibilities of the group in interacting with other groups. A thing or entity that makes sense within the context of the problem. For example, a student, a car, time, date concrete example of class is an instance of class. Class- a description of a group of similar objects contain fields that represent the properties(name, eye color) and behavior(responsibilities)(cook, clean) of the class. Instance of class- is a specific realization of any object. Method- a named algorithm that defines behavior (shop, cook) Filtering- the classes to find duplicates or remove unnecessary ones to find core classes in solution. Scenarios- are tried to be sure we understand collaborations.
