CS 1054 Introduction to Programming in Java (Spring 2008)

Lab 8: Console Input (and Aggregate classes)

Lab Objective

• Write a complete program that uses console input.
• Use an aggregate class.

Instructions

1. Begin by downloading Lab8.zip, save the file, and then extract it in a folder you can locate. Open this project in BlueJ. You will complete the BankConsole class, but leave the Bank and BankAccount classes intact (no revisions are necessary, nor ar they allowed).
2. Complete the BankConsole class such that it interactively carries out transactions on a Bank object through user input. You will need to use the Scanner class. Notice that BankConsole only calls methods on the Bank class, not from the BankAccount class. Here's a sample execution of the BankConsole class (letters in bold are a result of user input).

   deposit, withdraw, balance, or quit? balance
   account name: john
   Balance is 1000.0
   deposit, withdraw, balance, or quit? balance
   account name: marsha
   Balance is 2000.0
   deposit, withdraw, balance, or quit? deposit
   account name: john
   amount to deposit: 234.56
   deposit, withdraw, balance, or quit? withdraw
   account name: marsha
   amount to withdraw: 150.00
   deposit, withdraw, balance, or quit? balance
   account name: john
   Balance is 1234.56
   deposit, withdraw, balance, or quit? balance
   account name: marsha
   Balance is 1850.0
   deposit, withdraw, balance, or quit? deposit
   account name: bob
   amount to deposit: 100
   No account with that name
   deposit, withdraw, balance, or quit? quit
   Thank you.
   

   You do not have to follow the above demonstration exactly (i.e., you could use different messages or prompts), but you should retain all functionality.
3. Demonstrate your code to your TA when you are done.
