Question

3.11 (Modified Account Class) Modify class Account (Fig. 3.8 ) to

provide a method called withdraw that withdraws money from an

Account. Ensure that the withdrawal amount does not exceed the

Account’s balance. If it does, the balance should be left unchanged and

the method should print a message indicating "Withdrawal amount

exceeded account balance." Modify class AccountTest

(Fig. 3.9 ) to test method withdraw.

Answer 1

// method that withdraws (removes) only a valid amount to the balance
public void withdraw(double withdrawAmount) {
    if (withdrawAmount > 0.0) { // if the withdrawAmount is valid
        if(withdrawAmount <= balance)
            balance -= withdrawAmount; // removes it from the balance
        else
            System.out.println("Withdrawal amount exceeded account balance.");
    }
}
