I am no good at this

Question

Hello everyone out there on the internets. I am in my third week of a Java class. I am trying to show at least a small amount of progress to my instructor, so if anyone could tell me where my stupid mistakes are in this code it would be greatly appreaciated. I am getting an error in my constructor on line 36 I will put a comment there.
Thanx

Remove static from everything except main. Good point. The poster's code has the bad smell I dub:
static cling: you try to access a field/method from a
static context and get the syntax error "non-static
variable/method ... cannot be referenced from a static
context", so to get rid of that error you make the
field/method static but the error just spreads and clings to
your code until everything is declared static!
Your teacher will pull you up on this if you don't.Let's hope. But you may be expecting too much from some
teachers. We've had a few in these forums who were real
peaches.
