Question

I have a piece of coding I am working on for an assignment for uni and in truth I’m not that great with Java, but I have tried. I’m trying to get my try catch to work but it never seems to do what it is suppoes to. I think I have the exception wrong but I’m not sure which exception to use for the problem as I am trying to stop letters being typed in and just numbers.

The final problem I am having is I don’t know where to put this piece of coding:

 {
                   while (true)
        {
            cancel();
        }
 } 

I’m not sure in which part it is suppoes to go.

Any help would be greatly appricated.

This is my code, I’m sorry if it is a little messy.

Your code is very verbose – most of the comments are unnecessary (even though you may be urged to include them) So instead of:

minutesfromhours = 60*minutes;
                //To change the hours into minutes by diving the hour by 60 for departure.

You could write:

public final static int MINUTES_PER_HOUR = 60;
//...

minutes = MINUTES_PER_HOUR * hours;

When you have tidied the code it will be much easier to see the logic.
