Hi All,

     I have looked through the cutstock.java example and was curious as to why only array [] are used. Is there a reason that dynamic datastructures such as ArrayList is not used for storing handles to constraints and variables? For e.g.  IloRange[]   Fill = new IloRange[_amount.length]; is what is used in the cutstock.java example. What about something like ArrayList<IloRange> Fill = new ArrayList<IloRange>(); ?

    Any insight will be helpful and much appreciated.

Thanks,

There are two main reasons for this:

1. The example was written a long time ago. Back then Java did not have generics.
2. The CPLEX API is based on arrays, there are no overloads that take collection arguments.

Thus, if you feel that collections/generics fit better for your application, then by all means use them!
