I get an error when I try return new MyIterator() and I'm not sure what to do with the MyIterator constructor (have to define iterator based on a start node parameter). Any idea how to fix this? I know how to implement the next and hasNext.
I think I solved it....Thanks!!
You're defining a single constructor for your iterator, MyIterator(MyListNode<E> start). From your code, it's clear that the MyListNode<E> start argument is missing.
What I mean is, in this line:
return new MyIterator();
... you need to pass a reference to the first node in the list, something like this:
return new MyIterator(firstNode); // replace firstNode with the actual value
return new MyIterator(); you MUST pass as an argument a reference to the first node of the list, because that's how you defined the constructor. What to do with the first node, inside the Iterator? that's a different question. Hint: you need to store it in an attribute and make sure to implement hasNext and next accordingly.
