arrayset question, help please!

[christopher persinger]

I am supposed to be writing a method in a class called ArraySet that will do the following: Take a set as a parameter and substract the contents of that set from the current set if they exist in the current set. Then I would return the result as a new set. This is the code I have so far....

 public SetADT<T> difference (SetADT<T> set)
      {
         SetADT result = new SetADT();
         ArraySet<T> temp1 = new ArraySet<T>();
      
         T obj;
      
         temp1.addAll(this);
         Iterator<T> scan = set.iterator();
      
         while(scan.hasNext())
         {
            obj = scan.next();
            if(temp1.contains(obj))
            {
               result.add(obj);
            }
         }
      
         return result;
      }

What happens when you run this? What is your question?

Take a look at the
removeAll() method in the Set interface.
