“Sets” of a particular enum type but with generics

Question

Let\'s say I have an abstract class

public abstract class Trainer{}

I have specific trainers like :

pub         


        

Answer 1

Yes you can move your Trainables , Set completed and trainingComplete(Trainables t) to the class Trainer.

This way you no need to write these code each DogTrainer, HorseTrainer .. and so on...

 abstract class Trainer{
     public enum Trainables implements TrainingActions{
            BARK, BITE, ROLLOVER, FETCH;
     }
      public Set completed = new HashSet();
      public void trainingComplete(Trainables t){completed.add(t);}
}

Otherwise make trainingComplete(Trainables t) abstract and you need to implement in each Trainer implementaion clasees.

abstract class Trainer{
     public enum Trainables implements TrainingActions{
            BARK, BITE, ROLLOVER, FETCH;
     }
      public Set completed = new HashSet();
      abstract public void trainingComplete(Trainables t);
}

Now your DogTrainer and HorseTrainer are implementing trainingComplete(Trainables t)

 public class DogTrainer extends Trainer{      
     public void trainingComplete(Trainables t){
          completed.add(t);
     }
 }

 public class HorseTrainer extends Trainer{     
     public void trainingComplete(Trainables t){
           completed.add(t);
     }
 }
