Core Java Programming Course- Iterating on Maps

The video tutorial explains how to iterate over a map by first converting it into a set. It covers two methods: using a modified for loop and using an iterator. The tutorial demonstrates creating a tree map with integer keys and double values, iterating over it using both methods, and highlights that the tree map entries are sorted by keys. The video concludes with a brief mention of upcoming content on regular expressions.

Describe the role of the iterator when iterating over a map.

What is the outcome when running the program that iterates over the map?
