Why can't I output data from this array?

I need some help with how this array works:

    String[][] stringz = new String[5][4];
    System.out.println(stringz[x][y]);

When I try to output using stringz[1][3], I have the null data output.

when I try to output using stringz[0][3], I also have the null data output.

I know that in arrays index begins by 0.

So I also want to output the data in [0][4]

But java compilation shows me an error? Why? If i have 5 data boxes (5-1) = index #4 should be the last?

Your two dimensional array's indexes are below.

0,0__0,1__0,2__0,3

1,0__1,1__1,2__1,3

2,0__2,1__2,2__2,3

3,0__3,1__3,2__3,3

4,0__4,1__4,2__4,3

So, you don't have fourth index in your second dimension.
