Project: 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.
public class Test {
public static void main(String[] args) {
Account account = new Account(1122, 20000);
account.setAnnualInterestRate(4.5);
account.withdraw(2500);
account.deposit(3000);
System.out.println("Balance is " + account.getBalance());
System.out.println("Monthly interest is " +
account.getMonthlyInterest());
System.out.println("This account was created at " +
account.getDateCreated());
}
}
class Account {
// Implement the class here
}
