Betreff	Re: Can't make a static reference to nonstatic variable

---

anstelle klug über singleTon (wir sind bei Beginner!) zu Scheissen habe ich folgende Erklärung gefunden:
The issue is this: a static method means it belongs to the class, not each individual object. If you leave the static keyword off (the
usual case) as is done here with the method "myMethod()", it means that method can only be invoked on an object. But your call
from main() has not told myMethod() which object it is to be invoked on. Inside a non-static method, you don't have to provide
this information, as it assumes you mean the same object on which it was invoked. But when calling from a static method, you
must provide the information, and you haven't - hence the error message.

A common fix is to instantiate a member of the class, on which to invoke myMethod(), like this:


public static void main(String args[]) {

myclass m = new myclass();

m.myMethod();

}
