I am trying to calculate the minutesUsed of a phone call between two people. However I'm pretty sure that in my public void phone(Customer name, int callLength) there is an error but I am not sure where. It may have something to do with the fact that Customer name is never used? Here are the conditions:
- If either customer has a "pay-as-you-go" plan and the number of callLength minutes exceeds the minutesRemaining for either "pay-as-you-go" customer, then the call is not allowed ... nothing happens.
- After the method is called, both customers' minutesUsed amounts should increase by callLength minutes.
- If the call was successful, each customers' number of callsMade should increase by 1.
I don't know if my if statements are faulty but any help would be greatly appreciated. Thanks!
