What is the output of the given program?

public class ScopeTest
{
public static void main (String [] args)
{
int[][] xx[][][] = null;
System.out.println(xx);
}
}

This is the correct choice because an array variable (here xx) can very well have the null value. Null is the reserved constant used in Java to represent a void reference, i.e. a pointer to nothing. Internally, it is just a binary 0, but in the high level Java language, it is a magic constant, quite distinct from zero, that internally could have any representation. So, this answer is correct.
