Inspired by http://www.cs.unc.edu/~stotts/723/refactor/chap1.html - Problem: we want an output in HTML and the charging rule could change. - That long statement routine in the Customer does far too much. Many of the things that it does should really be done by the other classes. - Extracting the Amount Calculation (extract method) - Changing variables name - Moving the amount calculation from Customer to Rental - Removing "temp variable" with "query", clearer meaning. - Extracting Frequent Rental Points - Move method to Rental - Removing "temp variable" with "query", clearer meaning. - htmlStatement() - Moving the Rental Calculations to Movie - frequent renter points moved to Movie - static constructors to hide constants - inheritance & state pattern
