idea for this pls?!

[vivek sivakumar]

well i have a file say list.ini and following are the contents (contents might grow also..)
10002
10009
30000
40000
500000
600000
so my problem i need to read these values from this file and store it in a vector!!!pls give me an idea on how to do it?

Hello,
Here's a basic file reader that puts the data into a Vector:

import java.io.IOException;
import java.io.BufferedReader;
import java.io.FileReader;
import java.util.Vector;
 
class DeleteMe {

public static void main(String args[]) {

        try {
            
            Vector vector = new Vector();
            
            BufferedReader bufferedReader 
                        = new BufferedReader(new FileReader("list.ini"));
            
            String string;
            
            while ( (string = bufferedReader.readLine()) != null ) {
                
                vector.add(string);
                
            }
            
            for (int i = 0; i < vector.size(); i++) {
                
                System.out.println((String)vector.get(i));
                
            }
            
        } catch (IOException exception) {
            
            System.err.println("IOException: " + exception.toString());
            System.exit(1);
            
        }

}

}

You'd probably find lots of useful information if you were to do a search on the I/O and Streams Forum. The search page link is at the top right of this page.
Good Luck.

Also...
Chapters 21, 22, and 23 of Bradley Kjell's Java Tutorial do a decent job of covering the topics of file input and output.
And Chapter 10 of David J. Eck's Java Tutorial covers input and output in Java.
Good Luck.

This should do the trick...

import java.io.*;
import java.util.*;
 
public class IniReader
{
   public static void main(String[] args)
   {
      try
      {
         FileReader fr = new FileReader("list.ini");
         BufferedReader br = new BufferedReader(fr);
         Vector values = new Vector();
 
         String stringRead = br.readLine();
         while (stringRead != null)
         {
            values.add(stringRead);
            stringRead = br.readLine();
         }
 
         Iterator iter = values.iterator();
         while (iter.hasNext())
         {
            System.out.println(iter.next());
         }
      }
      catch (Exception e)
      {
         System.out.println("Exception caught: " + e);
      }
   }
}

If you have any questions, let me know.

Update: I see Dirk is a little faster on the draw than I am. Nice shootin', Tex!
