AP Computer Science --- Haas --- PiggyBank

Below are two classes. One defines a PiggyBank class, and the other class is a tester. Copy the two classes into BlueJ.

1. The method definitions in the PiggyBank class are not complete! Finish coding the incomplete methods.
2. Add a method addPennies which adds a given number of pennies to the PiggyBank.
3. Add a method getDollars which returns the value in the bank in whole dollars.
4. Add a method printContents which prints the total contents of the PiggyBank: numbers of pennies, nickles, dimes and quarters.
5. Add a method fewestCoins which changes the contents of the PiggyBank to the fewest number of coins without changing the total value.
   Example:
   If before fewestCoins is called: pennies=15 nickles=2 dimes=3 quarters=1
   then after fewestCoins is called: pennies=0 nickles=1 dimes=0 quarters=3
6. Add a constructor which allows the user to create a new PiggyBank with an initial number of pennies, nickles, dimes, and quarters.
7. Change the tester class to test all of the above enhancements.
