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:
