As per the subject, namely line //1

my main confusion is the face that f1 is a static variable and Object x is declared in a non-static method. I thouhgt only static methods could access static variables.

you've got it backwards:
* only non-static methods can access non-static variables.
* Static variables can be accessed by either static or non-static methods.
* and lastly, static methods can NOT access non-static variables.

Wilson, static methods have a problem with non-static variables, these are only accessible via an instance of the class.

Thanks, that makes more sense to me, I'm getting totally confused. I guess I incorrectly applied the law of contrapositive.
