Thread: Removing Line feeds or carriage returns

Hi All,

I have a requirement where I need to read a file with so many carriage return line feeds.
Attached is the file I am reading.

I have written a sample application to read the file and and remove these new line feeds but when I execute it, I see the line feed.

import java.io.*;
 
public class Main {
 
    public static void main(String[] args) throws IOException{
 
 
        BufferedReader br = null;
        PrintWriter sb = null;
 
        try{
            br = new BufferedReader(new FileReader("C:/Users/rejalu/Downloads/ATG/SubmittedOrders/2010/testfile.txt"));
            sb = new PrintWriter(new FileWriter("C:/Users/rejalu/Downloads/ATG/SubmittedOrders/2010/testfile3.txt"));
 
            String I;
 
            while((I = br.readLine())!= null){
                sb.println(I.replaceAll("[\\r|\\n]+", " "));
            }
        }
        finally
        {
               if (br!=null)
               {
                   br.close();
               }
            if (sb != null){
                sb.close();
            }
         }
 
 
        }
    }

Is there away to achieve this in attached output file?

This is just one record, but I have several records like these.

Thanks for your help.

This is what I see when I print the variable I

It is basically the same input file record I see being printed.

Create a simpler data file and work on that, something like:

Text file:
this is
is the
the file
file
to
work
on

Read each line and combine the next with the previous without the linefeeds so that the result should be:

this is is the the file file to work on

Show us that code and let us know what problems you're having with it. The code that successfully does this simpler example SHOULD work on the complex problem, though there may be complexities in the data file you haven't made clear.
