The video tutorial discusses three ways to iterate over lists in Java: using enhanced for loops, iterators, and streams. It explains the creation and use of ArrayLists, demonstrating how to print and modify list elements. The tutorial highlights the limitations of using enhanced for loops for list modification and recommends using iterators for safe deletions. The video concludes with a practical example of using an iterator to remove elements from a list.
