here is a way of reading your data:

"
  String tip = null;
  try
    {
    BufferedReader br = new BufferedReader(new FileReader("test.txt"));
    String str = null;
    while((str = br.readLine()) != null)
         {
         if (str.startsWith("LB ="))
                {
                tip = str.substring(4);  //removes the 'LB = '
                tip = tip.trim();  // tip is your values
                }
         }
    }
  catch(Exception ioe)
    {
...................................
    }

after that you have the values from your file
you can change them and then recreate your file based on the new values

with something like this:
"
        File file1 = new File("text.txt");
       FileOutputStream file = new FileOutputStream("text.txt",true);
       DataOutputStream out = new DataOutputStream(file);
       out.writeBytes(txt);   //txt is the content of your file
       out.flush();
"
also you'll have to include java.io.*

there are many other ways of  dealing with your problem.

i hope i was helpful to you

bye
