Customers are allowed to deposit money into an account (thereby increasing its balance), withdraw money from an account (thereby decreasing its balance), and earn interest on the account. Each account has an interest rate. Assume that you are writing a program that will calculate the amount of interest earned for a bank account. 1. Identify the potential classes in this problem domain. 2. Refine the list to include only the necessary class or classes for this problem. 3. Identify the responsibilities of the class or classes.
