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)
