Priting contents in BuferedReader

Posted by Divya on January 30, 2002 at 5:09 PM

Hi,
Try this code - I think this should solve your problem

import java.io.*;
public class JavaForum
{

public static void main(String args[])
{
String line = null;
StringBuffer concatStr = new StringBuffer();
try
{
BufferedReader fr = new BufferedReader(new FileReader("dat.txt"));
while((line = fr.readLine()) != null)
{
concatStr.append(line + " ");
}
System.out.println("File Contents are-->" + concatStr.toString());
}

catch(IOException e)
{
System.out.println(e.getMessage());
}

}
}

cheers,
Divya
