When I used to store my map as a 2D Array I could simply check the players position against the position in the 2D array (x, y) now that I read from a text file I'm not sure how to do so. Below is my code.

           String read = in.readLine();
           char letter = 0;
           
         for (int x = 0; x < 37; x++) {
            for (int y = 0; y < 15; y++) {
               if (read.charAt(y) == '1') {
                  if (read.charAt(x) == '1') {
                     g.drawImage(wall, (x - player.x) * width, (y - player.y) * height, null);
                  }
               }
            }
         }
      } catch (IOException e) {
         e.printStackTrace();
      }
   }
}


There are obvious errors in isBlockedWall, so I'm wondering how to rectify it.

Read the files content into the map[][] array when starting a map (I would suggest to add a loadMap(String location) method for this) and change your collision code back to the way it was.

Reading in a file on every draw() call is highly unwanted, since it limits your render speed to how fast your file can be read...
