(a) When you extends the javaAccount.java, you will need to override the super() constructors. (b) Add a static field called "minimumBalanceRequired" such that when account balance meets the minimumBalanceRequired, you get unlimited checking without fees. Otherwise, regular checking fees will apply. // hint: inside the withdraw() method, deduct a fee whenever the balance is below the minimum. (c) Add a static method to reset minimumBalanceRequired. (d) Add a new data fields called PIN# such that an internal PIN# has to match the input parameters before any transactions. Re-write the following methods with a PIN#: checkBalance(); deposit(), withdraw() and so on. (e) Add an implementation of the .toString() method to override any default methods: The toString() methods returns the premium account information #2. Add implementation of exception handling to the PremiumAccount.java class. (a) Inside each method with a PIN# input parameter, throw a appropriate exception object of your choice. (b) (OPTIONAL) Implement a new exception mechanism that allows only 3 consecutive trials of invalid PINs.
