You told Java wheere to find your class ( -classpath ...).
You didn't specify what class to use, so out.txt was used. This means
class txt in package out, which should be located at out\txt (which Java
will report as out/txt). This, of course, was wrong, and thus the
Exception.
Please specify the class that contains your main method.
Do NOT suffix the name with ".class" !
