First time Scanner Help

[Dex]

Hey guys this is my first time using scanners and I was wondering how you would scan something from a text file that is within a nested for loop.
e.g:

for (int i=0; i <ROWS; i++) {
        for (int j=0; j < COLS; j++) {
          if (twoDArray[i][j] == null) {
            pW.println("null");  // how would i scan this line 
          } else {
            pW.println(cards[i][j].getCardStatusInformation()); // and this line
          }
        }
      }

I think I already understand some of the basics of scanning, e.g

pW = new PrintWriter(fileName);
      pW.println(WidthOfWall);

could be scanned by:

 scan = new Scanner(fileName);
    WidthOfWall = scan.nextInt();

I hope this made sense, thanks.

I hope this made sense, thanks.

Scanner is used for reading data in. PrintWriter is for writing data out. So, no your post doesn't make sense. Btw, using a Scanner inside a nested for loop is exactly the same as using a Scanner inside a single loop or no loop at all for that matter.
