08:07 pm - Imagesevensoft - Sun Certified Java Programmer - Practice Question

I am making my way thru the Osborne book: Sun Certified Programmer & Developer for Java 2.

I took the practice test.
I got a question wrong that I'm going to post here. I don't see why my answer is wrong.

I'll post it and you guys can pick from the multiple choice in your comments.

I'll come back later and announce the "Correct" answer according to the book.
Given the following,

public class Test {
   public static void main(String [] args) {
   int [] [] [] x = new int [3] [] [];
   int i,j;
   x[0] = new int[4][];
   x[1] = new int[2][];
   x[2] = new int[5][];
   for (i=0; i<x.length; i++) {
      for (j=0; j<x[i].length; j++) {
         x[i][j] = new int [i + j + 1];
         System.out.println("size = " + x[i][j].length);
      }
   }
}

how many lines of output will be produced? (Choose one.)

A. 7
B. 9
C. 11
D. 13
E. Compilation Fails
F. An exception is thrown at runtime.

good luck!
