What is it that you like about the pattern that you want to keep? Are you
looking for static inner classes? You can couple the pattern with an
assisted inject factory, or providers depending on your use case.
public abstract class Action {
public abstract double doAction();
public static class ADD extends Action {
@Override
public double doAction() { ... }
}
public static class UPDATE extends Action {
@Override
public double doAction() { ... }
}
public static class DELETE extends Action {
@Override
public double doAction() { ... }
}
}
