The previous operation moves the cursor backward, whereas the next moves it forward. Thank you for your valuable feedback! Think of iterator as a cursor when you are typing text, imagine you had "abc" in some text file, and you want to read each and every one of those letters, at the very beginning cursor will be just before letter 'a' when you call next imagine that it moves one place to the right and selects the element it moves over, so you can now print that element or do something with it, then on the next call it will move over across 'b' so you can do something with 'b', and it keeps doing this until it has nothing to move over. This is a very useful construct in the multi-threaded programs - when we want to iterate over a list in a thread-safe way without an explicit synchronization. The Kubernetes ecosystem is huge and quite complex, so This, in turn, gives us a good pattern we can use in many methods that only requires collections processing while maintaining good cohesion and low coupling.
