I have 3 classes. BankAccount, InterestAccount and IsaAccount. InterestAccount extends BankAccount. IsaAccount extends InterestAccount.
This is what I have got for BankAccount for the withdraw method.
public void withdraw(int amount) {
balance = balance - amount;
}
This is what I have got in InterestAccount for the withdraw method. (minimumBalance is the amount belof which balance should not fall but don't worry about it)
public void withdraw(int amount) {
if (super.getBalance() - amount >= minimumBalance) {
super.withdraw(amount);
}
}
The question is what should I do to make a withdraw class for IsaAccount which kind of "extends twice"? I know super.super.balance isn't the case. What's the right way to do it?
