an exercise creating an account class in java. The Account Class
Problem Description: (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 field named balance for the account (default 0). • A private double data field named annualInterestRate that stores the current interest rate (default 0). Assume 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 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. Implement the class. 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.
Analysis: (Draw the UML diagram.)
