Do you know there are 5 different ways you can use to write code that iterates a Map in Java Collections framework? In this video, I'm happy to show you these 5 ways to iterate a Map in Java with simple and easy to understand code examples.
The 5 ways to iterate maps in Java are:

2. Use enhanced for loop on keySet
3. Use enhanced for loop on entrySet
