Iterating HashMap

Iterating over a HashMap is an essential operation when working with key-value pairs in Java. Since a HashMap does not guarantee any specific order of its elements, the iteration order may appear random. There are several ways to iterate over a HashMap, and each method offers different benefits. In this lesson, we will focus on two common approaches:

• Using keySet(): Iterate over the set of keys and then retrieve the corresponding values using the get() method.
• Using entrySet(): Directly iterate over the key-value pairs by using the set of Map
