Explanation / Answer

//Account.java class

import java.util.Date;

class Account
{
private int id;
private double balance;
private Date dateCreated;
private double anualInterestRate;
public Account()
{
Date dateCreated = new Date();
//System.out.println("toString(): " + now);
//System.out.println(dateFormat.format(dateCreated));
id=0;
balance=0;
anualInterestRate=0;
}
public Account(int id1,double bal)
{
dateCreated=new Date();
//System.out.println(dateFormat.format(dateCreated));
id=id1;
balance=bal;
}
public void set_id(int id1)
{
id=id1;
}
public void set_balance(double bal)
{
balance =bal;
}
public String getDateCreated()
{
return dateCreated.toString();
}
public void setAnnualInterestRate(double rate)
{
anualInterestRate=rate/100;
}
int get_id()
{
return id;
}
public double getBalance()
{
return balance;
}
public double getMonthlyInterestRate()
{
return anualInterestRate/12;
}
void withdraw(double amt)
{
balance-=amt;
}
void deposit(double amt)
{
balance+=amt;
}
}

----------------------------------------------------------

//Main.java

public class Main

{

public static void main(String[] args) {

//System.out.println("Hello World");

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.getMonthlyInterestRate());

System.out.println("This account was created at "+account.getDateCreated());

}

}

---------------------------------------------

//output

Balance is 20500.0   
Monthly interest is 0.00375
This account was created at Tue Sep 04 11:01:46 UTC 2018
