Error in the output file

Question

Hi,
I am pasting the code below. The main objective of this file is to accept three command line arguments 1st argument is data to be inserted into the file, 2nd argument is the position where the data has to be inserted and finally the file name to which the data has to be writen using RandomAccessFiles in Java.
When i try to write some data the data being written is in Hexadecimal. Kindly help me with respect to this.
Code goes as follows:
import java.io.*;
public class RandomFileTest
public static void main (String [ ] args)
String value = null;
long position = 0;
if (args.length < 3)
System.out.println ("Usage: java RandomFileTest value position
filename");
System.exit(0);
value = args[0];
position = Long.parseLong (args[1]);
RandomAccessFile file = null;
try {
file = new RandomAccessFile (args[2], "rw");
catch (FileNotFoundException ffe)
System.out.println("File not found. Will create it.");
if (position > 0 && position <= file.length ())
file.seek (position);
file.writeChars (value);
}

Answer 1

    try {
      file = new RandomAccessFile (args[2], "rw");
      if (position >= 0 && position <= file.length ()) {
        file.seek (position);
        file.writeChars (value);
    catch(IOException ioe) {
       System.out.println(ioe);
    }
