Default Initializing a ragged array during run time p197

Good evening,

I was wondering if someone would be so kind to explain the following code to me:

int[][] samples = new int [3][];

samples[0] = new int[count1];
samples[1] = new int[count2];
samples[2] = new int[count3];

for (i = 0; i<3; i++)
    samples[0][i] = i;
    samples[1][i] = i;
    samples[2][i] = i;
Note: the above code is on p197 (sorry if i have accidently copied it wrong)

I understand the first line where the actual array is declared, 3 rows and an undeclared number of columns.

(this is where im not sure im right)

ive understood the next section as basically selecting each row in the multi-dimensional array and declaring a 1D array (the count variable) in it. so the first row has 3 columns. the second row would have 10 columns etc.

(This is where im completely lost)

im assuming my understanding of the 2nd step is wrong as i dont understand what the last section is doing. Is it not creating an array which looks like



Thanks very much for taking the time to answer my question.
