Making abstract class an interface

[Ted Yu ted_yu-/[e-mail] [seajug]]

Hi,
There're currently two classes, A and B, which are both abstract and B extends A.
A has this method:

  public void setReversed(boolean reversed) {
    this.reversed = reversed;
  }
If I make A an interface and move the above method to B, what would happen to client code which was compiled against old API (extending B, not A) but is executed against jar built with new API ?

Thanks

You should be able to test this very easily yourself.
