I am trying to load an array from a tex file. The text file has as many lines as the array I must load has rows, and each line has as many characters as the array has columns. I won't have trouble with values higher than 9 because there are none in the text file.

The way I figured out to do it is by loading the file into a String array, then trying to convert that string, one-dimensional array into an integer two-dimensional array. This way:

Code:

String [] fase;

int [][] blocks;

 int [][] blocks = new int [8][8];
  String [] fase = loadStrings("fase.txt");
  
  for (int i = 0; i< 8; i++){
    for (int j = 0; j< 8; j++){
       blocks[i][j] = int(fase[i].charAt(j));
    }
  }
 

then I tried printing the values with:
Code:

  println(blocks[0][0]);
  println(blocks[7][7]);
 

wich should be 0 and then 3, but I got 48 and 51.

the text file is exactly this:
Code:

00111100
00100100
00100100
00100100
00100100
00100100
00111100
33333333 

what is going wrong?

the weird thing is that the code:
Code:

  String number = "3";
  int deriv = int(number);
  println(deriv);
 

returns 3.

But thanks.

yeah, that kinda makes sense

another thing

is there a way to read the "data" folder, so I can, for example, load a specific file that the user of the processing application will choose?

a way to read the number of files and their names?
