Can someone tell me what i am doing wrong?

[NJR]

hi,
I am trying to create a 2 dimmensional array that reads data from a text file using a buffer reader and tokenizer to separate the information in the text file. As far as using the buffer reader to read from text file it seems to work but when i try and introduce a tokenizer to read tokens i keep getting errors. Also i wanted it to display the data within the array eg:

file coordinates

x1,y1 = 0 [101][103]
x2,y2 = 1 [107][109]

and so on...

here is what is in the text file:

101    103    
107    109    
113    127    
131    137    
139    149    
151    157    
163    167    
173    179    
181    191    
193    197    

and this is the snippet of the code I am working on:

import java.io.*;
import java.util.*;
import java.lang.Math;

class try1
{
public static void print (int[][] array,int width)
      { int nrows = array.length;
    int ncols = array[0].length;
    for (int i=0; i<nrows; i++)
    {
       for (int j=0; j<ncols; j++)
       {
           String outputString = Integer.toString(array[i][j]);
        int length = outputString.length();
        if (length < width)
        for (int k = length; k < width; k++)
        System.out.print(" ");
        System.out.print(outputString + "\t");
    }
    System.out.println(" ");
    }
}
public static void main (String[]args)throws IOException
{
     String text;
     try
       {
    BufferedReader br = new BufferedReader(new FileReader("ex1.txt"));
             int counter, numberOfTokens = 20, number;
             while ((text = br.readLine()) != null)
    {
        System.out.println(text);
    }
    // Always close a file after opening.
        br.close();
      }
// Catch and handle the exception in the // event that the named file cannot be found.
    catch (FileNotFoundException fnfe)
    {
        System.out.println(fnfe);
        return;
    }
// Catch and handle an exception if there is // a problem reading the file.
    catch (IOException ioe)
    {
        System.out.println(ioe);
    }
      }
        StringTokenizer tokenizer = new StringTokenizer(br.readLine));            
 numberOfTokens = tokenizer.countTokens();
            while (numberOfTokens != 0)
            {
                for (counter=0; counter < numberOfTokens; counter++)
                {
         number = new Integer(tokenizer.nextToken()).intValue();number++;

                    System.out.print(number + " ");

                }
            System.out.println();
            tokenizer = new StringTokenizer(br.readLine());
            numberOfTokens = tokenizer.countTokens();
            }
}

What error are you getting?

I strongly recommend you to reorganize the StringToken section of code I've attached below because it is easy to make a logical error the way you have coded it. It is better to take this form instead:
// See the Java Almanac entry here

String aString = "word1 word2 word3";
    StringTokenizer parser = new StringTokenizer(aString);
    while (parser.hasMoreTokens()) {
        processWord(parser.nextToken());
    }

StringTokenizer tokenizer = new StringTokenizer(br.readLine));
numberOfTokens = tokenizer.countTokens();
while (numberOfTokens != 0)
{
for (counter=0; counter < numberOfTokens; counter++)
{
number = new Integer(tokenizer.nextToken()).intValue();number++;

System.out.print(number + " ");

}
System.out.println();
tokenizer = new StringTokenizer(br.readLine());
numberOfTokens = tokenizer.countTokens();
}
}
