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

d. 4

An Array Index OutOfBoundException is thrown.

I know the answer is d; however, can you explain line 2 of the code fragment? I am not sure why 4 is being printed.

**I figured it out. I was counting 1,2,3,4,5 when I should of been counting 0,1,2,3,4 for the rows and columns.
