Q77

Given the code fragment:

             int[][] array = {

                          { 0 },

                          { 0, 1 },

                          { 0, 2, 4 },

                          { 0, 3, 6, 9 },

                          { 0, 4, 8, 12, 16 } };

                          System.out.println(array[4][1]);

                          System.out.println(array[1][4]);

What is the result?

A.
4 null

B.
null 4

C.
An IllegalArgumentException is thrown at run time

D.
4
An ArrayIndexOutOfBoundException is thrown at run time

Risposta D

Infatti l'elemento 4° dell array 1 ( { 0, 1 }) non esiste e quindi si scatena un'eccezione.
