CMS 270 Object Oriented Design and Development Fall 2018 Assignment 3 Inheritance & Polymorphism Assigned Wednesday October 17, 2018 and Due Monday October 29 at 11:30 pm submit via Blackboard. Please DO NOT email them to me. you may submit as many times as you wish, before the deadline. Only your last submission will be graded, do ensure that this is your best version Objectives: The purpose of this assignment, is for students to demonstrate knowledge of Inheritance and polymorphism How inheritance works in Java how to build classes and sub-classes in Java How to read data from text files How to write data to text files How to use classes to create and manipulate objects Problem: You are required to simulate a batch processing system for a small, local Credit Union. The Credit Union manages 2 types of accounts: Savings, Checking accounts. All accounts have a number, an owner and a balance. Savings accounts have a minimum balance and a maintenance fee If the balance in the savings account ever goes below the minimum, the maintenance fee is charged once for the month until the situation is corrected Checking accounts have a last check issued, and last check used and a maximum number of checks allowed for the month. Transactions are executed on an account. A transaction has a type (which may be withdraw, transfer, deposit or close) Identify the classes that you need and their relationships. Code each of your classes including all of your getters and setters and any other helper methods that you think will be useful to solve the problem You may assume that you have 2 files available - account current status of all accounts; and batch.txt that contains a set of transactions to be performed on accoun contains information a he transactions in batch.txt are expected to reflect one month's worth of transactions Create a new class called BatchProcessor. BatchProcessor will be your driver class.
