But people often associate the idea of a HashMap with the object approach. Right? They do the same thing and ideally have the same time complexity, but it comes down to the methods and storage. How do you create

In this code, we again create a HashMap and fill it with key-value pairs. The entrySet() method provides a Set of entries, which we can loop through. Each entry allows us to call getKey() to retrieve the key. This method is particularly useful when you need to work with both keys...
