Lab Assignment 5

1.(10pt) 11.23(c)

• Again, read the text from a file.
• You don't have to do any sorting.
• First use HashMap, and then replace it with TreeMap and see whether there's any difference in output.
  

3.(10pt)  Write two exception classes, AccountDepositException and AccountWithdrawException, and modify the Account class such that

• deposit() throws AccountDepositException when the amount to be deposit is negative
• withdraw() throws AccountWithdrawException when the amount to be withdrawn is negative or greater than the balance
• transfer() handles both deposit and withdraw failures properly (taking advantage of exception handling, of course).
