hi,
From your previous post
http://forum.java.sun.com/thread.jspa?threadID=5226088you are trying to write in a file and add some text before last line in that file,
if yes
here is the modified code,
try to even better;
file.java
import java.io.*;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.Vector;
import java.util.Enumeration;
public class file
public static void main(String args[]) throws IOException
InputStream in = new FileInputStream("out2.txt");
FileWriter fo=new FileWriter("out3.txt");
Vector v = new Vector ();
int c,pos,pos1;
String s=new String();
StringBuffer sb = new StringBuffer();
while((c=in.read())!=-1)
sb.insert(0,(char)c);
sb = sb.reverse();
s = sb.toString();
pos = s.indexOf("verify scan_test",0);
s=s.substring(pos+1);
int linecount = 0;
while (pos >= 0) {
            s = s.substring(pos + 1);
            pos = s.indexOf("_cpdp_=", pos);
            pos = s.indexOf("=", pos);
            pos1 = s.indexOf(';', pos);
            v.add(s.substring(pos + 1, pos1));
               ++linecount;
Enumeration e = v.elements ();
String str = "";
while ( e.hasMoreElements())
{   --linecount;
     if( linecount == 0)
          str = "what code you to add here \n\r" + e.nextElement ();
     else
          str = e.nextElement().toString();
     fo.write( str +"\n\r" );
fo.close();
out2.txt
verify scan_test  {
  Abb {* verify:0  Value:0  lifecycle:0 *}
  W tset_tp;
  S {  _cpdp_=YYYY10YYYYYYYYYYYYYYYYYYY;
  Abb {* Begin loop test *}
  S {  _cpdp_=YYYY10YYYYYYYYYYYYYYYYYYY;
  S {  _cpdp_=YYYY110YY1YYYYYYYYYYYYYYY;
  S {  _cpdp_=YYYY110YY1YYYYYYYYYYYYYYY;
  S {  _cpdp_=YYYY111YY1YYYYYYYYYYYYYYY;
  }i hope it will give you a clear cut idea
