I have a method which prints the Type and Value fields from selection of Car objects.
Then I need to total the value of multiple forcourts by calling getForecourtYValue(), getForecourtZValue(). (Don't worry my code is much cleaner than this im trying to provide an example which is unrealted to my code).
And then I will print the combined value of these forecourts. In my summing method I just call each function which adds up each individual forecourt and thus minimises code duplication, but it does print each forecourts listings twice (i'm using Test Driven Design).
How can I avoid a function which is called printing its output?
