Basically I have a custom List class that contains different fruits. Assume that each fruit has an ID number that is stored in the list.

Is it better to have:

new AppleList(); new OrangeList(); new LemonList();

or

new FruitList<Fruit.Apple>(); new FruitList<Fruit.Orange>(); new FruitList<Fruit.Lemon>();

Things to consider:

  • All IDs are of type int.
  • The type of the fruit will not affect the implementation of the List itself. It will only be used by the client of the list, like an external method, etc.

I would like to use the one that is clearer, better in design, faster, more efficient, etc. Additionally if these above 2 techniques are not the best, please suggest your ideas.

EDIT: Btw Fruit is an enum if that wasn’t clear.

  1. •All IDs are of type int.

    •The type of the fruit will not affect the implementation of the List itself. It will only be used by the client of the list, like an external method, etc.

    Given these two facts, I wouldn’t bother with generics. I would put a normal property on FruitList to indicate which type of fruit it is.
