I have a class that has 2 properties that take integer values. In the main code stream, I'm writing a loop through which to record list of n instances of the class. Then I suppose you need to sort these instances by any field. And I need it to apply? Create a separate class for sorting? Just in the main code stream(progtam) to write this sort? Or in the main thread code to execute it as a procedure?And the same with all the other things, I/o, etc. As everything is made? In a separate procedure, or also with classes?
