Chapter 12, Problem 4E

Repeat Exercises 6 and 7 in Chapter 7, but use an instance of ArrayList instead of an array. We will no longer need to know the maximum number of sales, so the methods will change to reflect this.

Blurred answer
Students have asked these similar questions
Challenge exercise What are examples of other methods that the Arrays class provides?
Write assignments to the library, cs101, and track variables (which you defined in the previous three exercises) to create the appropriate ArrayList objects. Write them once using diamond notation and once without diamond notation, specifying the full type.
Challenge exercise Read the footnote about the Arrays. asList method. Find and read the sections later in this chapter about class -variables and class methods. Explain in your own words how this works.
