Question

Design a class named Account that contains:

-private int data field named id for the account (default 0)

-private double data field named balance for the account (default 0)

-private double field named annualInterest Rate that store the current interest rate(default 0) Assume all accounts have the same interest rate

-private Date field named dateCreated that store the date when the account was created.

-default constructor that creates a default account

-constructor that creates a account with the specified id & initial balance.

-Accessor & mutator methods for id, balance, & annualInterestRate

-Accessor method for dateCreated

-Method named getMonthly InterestRate( that returns the monthly interest rate

-Method names getMonthlyInterest() that returns the monthly interest

-method named withdraw that withdraws a specified amount from the account

-method named deposit that deposits a specific amount to the account

-Write a test demo program that creates an Account object with an ID of 1122, a balance of $20,000.00, & an annual interest rate of 4.5%.

-Use the withdraw method to withdraw $2,500 & use the deposit method to deposit $3,000, $ print the balance, the monthly interest, & the date when this account was created.

Explanation / Answer

class Account
{
private:
int id;
double balance;
double annualInterestRate;

Date dateCreated;

Account()
{
this.id=0;
this.balance=0.0;
this.annualInterestRate=0.0;
}

Account(int id, double balance)
{
this.id = id;
this.balance = balance;
}

void setId(int id)
{
this.id = id;
}

int getId()
{
return this.id;
}

void setBalance(double balance)
{
this.balance = balance;
}

double getBalance()
{
return balance;
}

void setAnnualInterestRate(double annualInterestRate)
{
this.annualInterestRate= annualInterestRate;
}

Date getDatecreated()
{
return this.dateCreated();
}

double getMonthlyInterestRate()
{
double monthly = this.annualInterestRate/12;
return monthly;
}

double getMonthlyInterest()
{
double amount = (this.balance *this.annualInterestRate *100)/12;
return amount;
}

double withDraw(doubel amount)
{
this.balance-= amount;
return this.balance;
}

double deposit(double amount)
{
this.balance+= amount;
return this.balance;
}

public static void main(String args[])
{
Account acc = new Account(1122,20000.00);
acc.setAnnualInterestRate(4.5);

double withDraw = acc.withDraw(2500.00);
double deposit = acc.deposit(3000.00);

System.out.println("Balance after withdrawing amount is " + withDraw);
System.out.println("Balance after depositing amount is " + deposit);
System.out.println("Date accoutn created " + acc.getDateCreated());
System.out.println("Monthly Interest " + acc.getMonthlyInterest());

}
