Perceptual complexity of object oriented systems: a student view

ion Class Design Encapsulation, intra class complexity, proper placement of methods and attributes, choice of class protocol. Labels or names of attributes and methods. Number of attributes, etc. Use of global variables, polymorphism, or information hiding. CD.2 number of methods per class CD.6 class vs instance variables what to put in each CD.7 Polymorphism and information hiding CD.10 underloading methods (i.e., no polymorphism) CD.11 over-overloading methods: too much polymorphism CD.12 over-over-over loading resulting in chaos CD.14 information hiding vs encapsulation, same? CD.15 attributes in the wrong place Method Design The length of the method in lines of code, number of arguments, and placement of the methods in appropriate classes within the class hierarchy. MD.1 length of the method short vs long: how much does it do? MD.3 overwriting methods MD.4 length of methods MD.6 overloading methods
