Patni Java Based Interview for EXperienced People..

Answer / pankaj desai

A JSP is actually a class. This means that if we define a
class within a JSP, it is actually an inner class.
Remember that inner classes cannot have static methods, so
you can't declare main() like this:

public static void main() { }

We know that the inner class won't have access to out, so
we can either create an instance variable

Is This Answer Correct ?

7 Yes
