Empty 2D array from another class

Hi all, I'm actually equating a 2D array from a class to another class. I call it using method call. However, it seems like the 2D array is empty after I equate it to another 2D array in another class. May I know where is the problem?

I actually want the stored values in the 2D array in line 96, to be brought over to the 2D array in line 203. I used method call in line 152 and 153 to return the 2D array myDouble, and equate the method call to the 2D array in line 203. However, I realised my 2D array in line 96 is empty after it is out of the for loop. May I know how can I still store the values in it and call it elsewhere even when it is out of the for loop?

Because you are using iterator but you never increase value of x and y you are using in the loop.

Insert y=0; before line 92
Insert y++; after line 96
Insert x++; before line 98
