Question

Is it possible to convert or typecast a char array “gg[16][16]” to an object array “ff[16][16]”?

charToObject() and toObject() are both mostly used for single values.

Should this simply work:

Object[][] ff = (Object [][])(gg [16][16]);

Answer 1

Since it’s a 2d array you need a nested for loop that look something like this:

for(int i=0; i<gg.length; i++)
  for(int j=0; j<gg[i].length; j++)
    gg[i][j]=ff[i][j];

assuming that gg is your original array, and ff is the new one. This will start by checking all “rows” in the first “column” of the array and assign that to the proper part of the new array, then continue looping thru the second “column” and assigning all “rows” that belongs to that column etc.
