How can you have access to the private member of the Suits enum on line 13?


Thank you in advance for helping clear this up.

Yes because it is an inner enum.
This, OTOH

would produce a compiler error.

You are right, that it doesn't print anything meaningful, but that was part of the difficulty with choosing the proper answers as well. The available answers were as follows:

Which are true? (Choose all that apply)
A. The output could contain 30
B. The output could contain @bf73fa
C. The output could contain DIAMONDS
D. Compilation fails due to an error on line 6
E. Compilation fails due to an error on line 7
F. Compilation fails due to an error on line 8
and so on

The correct answers were A and B because of how some of the output was unpredictable like you mentioned. You are also correct in stating that using Arrays.asList() will print valuable output as opposed to Suits.values()
