Your are asked to design and implement a simple program that models the operations of a bank. Each bank account has one account owner. The bank distinguishes between two types of account owners, student and non student (person) and three types of accounts - a basic account type, a studentaccount type for students, and a high roller account type for anyone with high balance. The skeleton of the code has been provided. Please complete it.

Hints: Quite a bit of the design has already been done for you. Make sure you understand well the OOP concepts of composition, inheritance and polymorphism before you write any code. Start with implementing the Person class and then Student. Then implement BasicAccount, StudentAccount and HighRollerAccount. Finally implement Bank. Build incrementally and test each component well in your Main class before you move on to the next.

Main

public class Main { public static void main(String[] args) { Bank b = new Bank("Bank of Rupt"); b.setIntRate(0.1); b.setMaintFee(50); Person bob = new Person(11315, "Bob"); int bobAcctId = b.openAccount(bob, 1000); Person alice = new Student(12512, "Alice", "SMC", 1234); int aliceAcctId = b.openAccount(alice, 500); Person rich = new Person(51542, "Rich P. Person"); int richAcctId = b.openAccount(rich, 1000000); Person richStudent = new Student(23814, "Rich S. Student", "USC", 1191); int richStudentAcctId = b.openAccount(richStudent, 100100); // another account for Rich S. Student b.openAccount(richStudent, 30000); // another account for Alice b.openAccount(alice, 100); // another account for Bob b.openAccount(bob, 5000); System.out.println("All the accounts: "); b.printAllAccounts(); System.out.println(); System.out.println("All the accounts of Alice: "); b.printAccountsForOwner(alice); System.out.println(); System.out.println("Paying interest : "); b.payInterest(); b.printAllAccounts(); System.out.println(); System.out.println("Assessing maintenance fees: "); b.assessMaintenanceFee(); b.printAllAccounts(); System.out.println(); System.out.println("Rich P. Person buys a Ferrari, Alice wins the lottery, Rich. S. Student pays tuition ..."); b.withdraw(richAcctId, 331000); b.printAccountsForOwner(rich); b.deposit(aliceAcctId, 100000); b.printAccountsForOwner(alice); b.withdraw(richStudentAcctId, 45000); b.printAccountsForOwner(richStudent); System.out.println(); } }

HighRollerAccount

public HighRollerAccount(int id, Person owner, String bank, double balance) { // your code here } // your code here // override the toString method to return: "High Roller " + whatever the basic account returns // your code here

StudentAccount
