Consider the following class declaration: public class Square { private double sideLength; public double getArea() { return sideLength * sideLength; } public double getSideLength() { return sideLength; } } Write a no-arg constructor for this class. It should assign the sideLength field the value 0.0. Write an overloaded constructor for this class. It should accept an argument that is copied into the sideLength field. Look at the following description of a problem domain: The bank offers the following types of accounts to its customers: savings accounts, checking accounts, and money market accounts. 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 an application that will calculate the amount of interest earned for a bank account. Identify the potential classes in this problem domain. Refine the list to include only the necessary class or classes for this problem. Identify the responsibilities of the class or classes.
