Question
Please answer 8.7 and 11.3 seperately.
(The Account class) Design a class named Account that contains: A private int data field named id for the account (default 0). A private double data Held named balance for the account (default 0). À private double data field named annual Interest Rate that stores the current interest rate (default 0). Assume all accounts have the same interest rate. A private Date data field named date Created that stores the date when the account was created. A no - arg constructor that creates a default account. A constructor that creates an account with the specified id and initial balance. The accessor and mutator methods for id, balance, and annual Interest Rate. The accessor method for date Created. A method named getMonthlylnterest Rate () that returns the monthly interest rate. A method named getMonthlylnterest () that returns the monthly interest. A method named withdraw that withdraws a specified amount from the account. A method named deposit that deposits a specified amount to the account. Draw the UML diagram for the class and then implement the class. (Hint: The method getMonthlylnterest () is to return monthly interest, not the interest rate. Monthly interest is balance * monthlylnterestRate. monthlylnterestRate is annual InterestRate / 12. Note that annual InterestRate is a percentage, e.g.,like 4.5%. You need to divide it by 100.) Write a test program that creates an Account object with an account ID of 1122, a balance of S20,000, and an annual interest rate of 4.5%. Use the withdraw method to withdraw S2,500, use the deposit method to deposit S3,000, and print the balance, the monthly interest, and the date when this account was created. (subclasses of accounts) In programming Exercise8.7 the account class was defined to model a bank account. An account has the properties account number, balance, annual interest, and date created, and method to deposite and withdraw funds. Create two subclasses for checking and saving accounts. A checking account has an overdraft limit but a savings account cannot be overdrawn Draw the u ml diagram for the classes and then implement them. Write a test program that creates objetes of account, savings account, and checking-account and invokes their toString()methods
