Design a class named Account that contains: ▪ A private int data field named id for the account (default 0). ▪ A private double data field named balance for the account (default 0). ▪ A private double data field named annualInterestRate that stores the current interest rate (default 0). Assume that all accounts have the same interest rate. ▪ A private Date data field named dateCreated 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 annualInterestRate. ■ The accessor method for dateCreated. ▪ A method named getMonthlyInterestRate() that returns the monthly interest rate. ▪ A method named getMonthlyInterest () 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 then implement the class. (HINT: The method getMonthlyInterest() is to return monthly interest, not the interest rate. Monthly interest is balance * monthlyInterestRate. monthlyInterestRate is annualInterestRate / 12. Note annualInterestRate is a percentage, for example 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 $20,000, and an annual interest rate of 4.5%. Use the withdraw method to withdraw $2,500, use the deposit method to deposit $3,000, and print the balance, the monthly interest, and the date when this account was created.
