Provide an iterator over the contents of two lists simultaneously?

Question

Suppose I have this:

public class Unit {

    ...

    List mobileSuits;
    List pilots;

    ...
}
         


        

Answer 1

Why not have a class MannedMobileSuit as a subclass of MobileSuit that contains an instance of a pilot ? That would solve your problem by having a getPilot method.

Usually when you get such problems (needing to return two instances) it is because your Object model is not appropriate and should be changed. Keep your options open
