What is the Iterator in Java's Collection Framework?

Can you explain what the Iterator is in Java's Collection Framework?

Sure! The Iterator is an interface in Java that allows you to traverse through a collection, like a list or set, without exposing the underlying structure.

How do I use the Iterator to loop through a list?

You can use the hasNext() and next() methods of the Iterator. First, create an Iterator object from your list, then use a while loop to iterate through it.

Can you show me a code example?

Absolutely! Here's a simple example:

List<String> list = new ArrayList<>();
list.add("Apple");
list.add("Banana");
Iterator<String> iterator = list.iterator();
while (iterator.hasNext()) {
    System.out.println(iterator.next());
}

What are the advantages of using an Iterator?

Using an Iterator provides a uniform way to traverse different types of collections, and it also allows for safe removal of elements during iteration.
