You need to have the main method in a public class.

[pbl]

which match the name of the .java file

[fromTheSprawl]

In short, add public to your class name definition, and put it in a file named with your class name and with an extension of .java.

Actually does not really need to be public, can be protected

Just move the main() class to farhan and it will work

That's new to me, thanks! I'll probably read up on it once I reach classes on the Java Tutorials.

[pbl]

fromTheSprawl examples that are showed in this forum are always extreme and do not reflect what you would see in real life.

In real life nobody would bother extend a class which have only a few lines (but for educational purposes) so in real life clas farghan would have a few dozens lines
so nobody would extend it in the same .java file

so the showed case would never happen in real life

[fromTheSprawl]

Well, as much as possible I would like to know as much as how stuff works in Java, like this one, I think it is simple but I didn't know that it could still run without the public class. I might have misguided him if not for your correction.
