Error when defining iterator/iterator constructor?

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
