Marcus Exam 2

[Hassan Naqvi]

Hello Friends,
I can't understand the philosphy of Marcus(Infact JVM) for the following question.

1: 
public class Arg{
String[] MyArg;
        public static void main(String argv[]){
        MyArg=argv;  //lINE 1
        }
        public void amethod(){
                System.out.println(argv[1])
}
}

Ans: Compile time error
Explanation:
You will get an error saying something like "Cant make a static reference to a non static variable".
Note that the main method is static. Even if main was not static the array argv is local to the main
method and would thus not be visible within amethod.
Regards,
Hassan.

Hassan,
What is that you did not understand here?As the explaination goes,argv[] is of course local to the main method and amethod can access MyArg but not argv[].Also since MyArg[] is non static,you cannot access it directly without creating an instance of the class Arg.

Got it!!

argv is a local variable only accessible within main method!
