It says that the right answer is:
The program will print no arguments and 1 arguments when called with zero and one arguments.
Is there any possible way to run a java file with no argument and 1(as an argument) at the same time?

No, it will print "no arguments" when run with zero argument and "1 arguments" when run with one argument.

Thanks, it is probably the way the sentence is set (from the grammatical POV...) that confused me....

This question is incorrect.
Code: Select all
class SomeClass{
public static void main( String args[ ] ){
if (args.length == 0 ){
System.out.println("no arguments") ;
}
else{
System.out.println( args.length + " arguments") ;
}
}
}
The correct answer is: The program will fail to compile.
Reason: "args.length" is the improper use of the String method length().
The correct use of length() is args.length().
Can someone from enthuware confirm this. I just purchased you software and this is concerning to me.

The question is correct. args is an array.
Please try it out.
Also, I will suggest you to go through a book before attempting the mock exams because you have asked a very fundamental question.
