Java - NetBeans IDE 8.2

So i have an error in my code, but there are no red squiggly lines throughout the program. When i try to run my code it says there is no main class? My logic throughout the code seems fine though, i need to finish a couple parts but i only care about the no main class part at the moment. I'm guessing i just set up the project wrong? Any and all help is greatly appreciated, i would post the code but it says it is too long to be posted.
