Hi Munashe Mandizvidza

Thanks for asking about for-each loop also known as Enhanced for Loop. You can use it especially with Collections such as Lists. for-each loop loops through each item in the list and stores each item in a variable - in this case, it stores each dog name in a String variable.

The loop begins with the keyword for followed by the brackets. Inside the brackets you need to declare the variable name and type to store each item in the list. Next, use a semi-colon and put the list or the array to loop.

Please see my example for this challenge:

for (String name: dogNames)

Let me know if this clarifies.

This is answering another question than the one asked.

The answer to the question is List <Rock> Which draws from the Rock class below.
