Hi,
Try this piece of code, import java.io.*;
class Offset {
     public static void main(String a[]) {
          int lineNo=Integer.parseInt(a[0]); // Pass the line no as an argument
          Offset offset = new Offset();
          long os = offset.getLineOffset(lineNo);
          System.out.println("Offset is : "+os);
     private long getLineOffset(int lineNo) {
          int count = 0;
          String line = "";
          long lineOffset = 0;
          try {
               File file = new File("test.txt");
               BufferedReader br = new BufferedReader(new FileReader(file));
               line = br.readLine();
               while(line != null) {
                    count++;
                    if(count == lineNo)
                         break;
                    lineOffset += line.length();
                    line = br.readLine();
          } catch(Exception e) {
               System.out.println(e);
          return lineOffset+1;
