You never replied to my question in your last thread, and you never replied to *any* answers to your first thread. Sorry, but it can be de-motivating to a volunteer if they feel their help is being ignored, that they're wasting energy and time for no reason as it begs the question how will we know if you'll read and reply to help in this thread?

Did you resolve the issue from the previous threads? If so, please don't leave us hanging; please let us know. Or is the issue still not solved? If not, please let us know that too and anything that we can do to help you solve it.

Regarding the current problem, I think that you'll need to tell us more about the problem as you've posted quite a lot of code and only have given us a small bit of explanation. Also, what steps have you taken to debug the problem? Are you using a debugger or using println statements to help debug?

wow that's a lot of code to just be a main method u should break some of the stuff you've written down (like every option choice) into separate classes.... makes it easier for others to read.... i can see from it that the reason you can't book another room in the house is because of "else if (roomNumber == 2){if (HouseA1[roomNumber-2] < 2 ) {HouseA1 [roomNumber-2] += 1;...." when u enter 2 the program executes HouseA1[roomNumber-2] which is HouseA1[0] which is already booked

And you still haven't replied to the previous posts or the current ones. I was hoping that you would have proved me wrong in this and would have shown all what a great guy you were by acknowledging all the contributions that have been posted in your threads in an attempt to help you be a better coder, and yet you still disappoint me.

Please surprise me by rectifying this problem. I know you can do it. I know that we can transform you into a model forum citizen.

With hope, Curmudgeon.
