You can review the topics of this hour more fully with the following activities:
Write a short Java program called Favorite that puts the code from this hour's "Comparing Two Strings" section into the main() block statement. Test it out to make sure it works as described and says that Ada's favorite instrument is not the ukelele. When you're done, change the initial value of the guess variable from ukelele to piano. See what happens.
Modify the Credits program so that the names of the director and all performers are displayed entirely in uppercase letters.
