TASKS:

1. Name your Project: "FinalProject".

2. Create a package within your Project called "BrokeragePkg".

3. You should have 4 classes in the BrokeragePkg: Brokerage, Portfolio, Stock, and FinalProject_MainClass.

4. The Brokerage class should contain a construtor and a private String brokerageName attribute with appropriate getter/setter methods, along with a public Portfolio ArrayList attribute.

5. The Portfolio and Stock classes should be very much as you have them for your earlier programs, but change the doubles to ints for previousClosingPrice and currentPrice, and their methods, as well. The Portfolio class should have a private int portfolioID attribute.

6. Inside the FinalProject_MainClass I've given you, change the direct-access calls to data members so that they use the get() and set() methods of your classes.

7. Add to the inner for-loop output the change percentage functionality you did for your Stock program (the last output line is println() you'll notice.. the others are simply print(), keep that in mind for proper formatting).
