Android: enum vs static final ints?

Question

What are the advantages (or disadvantages) of having an enum versus having a set of static final ints in Java Android applications? Are there efficienc

Answer 1

One advantage of ints over enums is in a CLASS FACTORY. The following C# code is not extensible:

class Factory
{
    public enum DrawableType {CIRCLE,SQUARE};
    public static Drawable GetInstance(DrawableEnum e)
    {
        if (e == DrawableType.CIRCLE)
        {
            return new Circle();
        }
        else if (e == DrawableType.SQUARE)
        {
            return new Square();
        }
        else
        {
            throw new IndexOutOfRangeException(); // should never get here
        }
    }

I wrote this poor code. Reviewing Design Patterns, the gang of four used an int. I tried to recover here.
