Exception catching

The bold is where I am having trouble (beginning at line 19 ending at 36). At first, I was trying to make my boolean I yes or no instead of true or false. When I couldn't figure that out I decided to do a try-catch to prompt the user to enter true or false.
Two things happened. 1st the "inService" variable in line 36 now says it couldn't be resolved. So I used the eclipse suggestion and created a field for 'inService'. When I ran the program and got to t that part the loop never stopped, I had to terminate the console manually.

I'm going to have to implement a try-catch for the rooms also to make sure the user doesn't input a string such as "three" instead of "3". I was going to use this same method but I can't get this one working.

Any help or advice would be greatly appreciated.

The user can type in either "yes" or "no" and you can turn that into a boolean by checking if it is equals() to "yes" or "no":
