Assume that the following two classes are compiled and run. What is the output?

You don’t have to provide a formal trace—you just have to show the output. But to determine the output, you’ll need to do an informal trace either in your head or with a few notes. You are encouraged to verify your answer by running the program on a computer. Running the program is for verification purposes, not for coming up with the answer in the first place. You should be able to understand how the program works by just examining its code.
