The java programing question goes like this:

Write two classes to describe BankAccount objects.

A bank account is described by the account owner's name, an account ID (stored as text), and the balance in the account.

A savings account is a type of bank account that is described by this same information and also by an interest rate.

In each class, include (or use inherited versions of):

instance data variables

two constructors

one constructor takes a starting balance; the second constructor creates an account with no money

you decide what other parameters should be included in each

getters and setters

include appropriate value checks when applicable

a toString method

you decide the output

a deposit method

include appropriate value checks

a withdrawal method

include appropriate value check

I already did some part:

public class SavingsAccount extends BankAccount {

private double interestRate;

private double minBalance;

// private static final double DEFAULD_BALANCE = 0.00;

public SavingsAccount(String name, String id, double balance, double interestRate, double minBalance) {

super(name, id, balance);

this.interestRate = interestRate;

this.minBalance = minBalance;

}

/*

* public SavingsAccount(String name, String id,double interestRate){

*

* this(name, id, DEFAULD_BALANCE, interestRate); }

*/

public double getInterestRate() {

return interestRate;

}

@Override

public void setBalance(double newBalance) {

if (newBalance >= minBalance) {

balance = newBalance;

}else {

System.out.println("Invalid Value.");

}

}

public void setInterstRate(double newInterestRate) {

interestRate = newInterestRate;

}

@Override

public String toString() {

String s = super.toString() + "\tInterest Rate: " + interestRate;

return s;

}

@Override

public boolean withdrawal(double withdrawleValue) {

if ((balance - withdrawleValue) >= minBalance) {

return super.withdrawal(withdrawleValue);

} else {

System.out.println("Banlance cannot be less than minimun balance. ");

return false;

}

}

}

My question is :

Include a minimum balance as part of what describes a savings account. Update the class as necessary, making sure that the account is not allowed to go below this minimum balance. (use the saving account program above)
