Iterator and linked list

Question

I'm making a college project in which I can't use Java API , so I need to create my own linked list.

Besides, other requirement is use a iterator with the list.

What is exactly a iterator? Why is important to use a iterator with a linked list?

I will use the iterator to all actions in my list, like add a link and etc?
