I am primarily a C++ programmer, but for work I have been using a lot more Java recently. It's is mostly not a big deal, but some stuff throws me for a loop. I keep seeing the error "non-static variable this cannot be referenced from a static context." Why do I keep getting this error?

A non-static variable only exists when there is an instance of an object. If you have a static method, it can NOT get to any variable in a class object unless it has an example of that class and uses that to get to the variable.

The solution for you is that you either make your fields static or your methods non-static. You main could look like this then:

class Programm {
    public static void main(String[] args) {
        Programm programm = new Programm();
        programm.start();
    }
    public void start() {
        // can now access non-static fields
    }
}
