Java games rock!


« Posted 2004-07-24 19:05:35 »

Hey, i'm pretty new to java, and i need some help with a simple maze game that i'm trying to do.  First, i want to draw a maze by reading from a file, and storing that information into a 2d array.  The fill will have 1s and 2, where 1 represents a wall and 2 represents a corridor.  Here is what i have so far:
     StringTokenizer tokenizer;
     String line, file = "map.txt";

     int map [][] = new int [13][15];

     try
             {
                 FileReader fr = new FileReader(file);
                 BufferedReader inFile = new BufferedReader (fr);
                 line = inFile.readLine();
                 
                 while (line != null)
                  {
                       tokenizer = new StringTokenizer (line);
                       for(int row = 0; row < 13; row++)
                        {      
                             for (int col = 0; row < 15;col++)
                              {
                             map[row][col]=Integer.parseInt (tokenizer.nextToken());
                             }
                         }
                       line = inFile.readLine();
                 }                   
                 inFile.close();
            }
           catch (FileNotFoundException exception)
            {
                 System.out.println ("The file " + file + " was not found.");
            }
           catch (IOException exception)
            {
                 System.out.println (exception);
            }
      }

The problem is, when i run appletviewer, i get a NoSuchElementException,  if anyone can help, i'd be really greatful

Just print the lines as you process them and you will likely see why you are running past the last token.

for (int col = 0; row < 15;col++)


This looks like a typo to me...
