Posted: Oct 7, 2003 9:28 PM

Hi!Can somebody help me with that.I need to read from a file and display its contents by reversing them.ex:i read John Smith form file i need to display Smith,John.
My code is not working.Is there anything wrong with it?

import java.io.*;
import java.applet.Applet;
import java.awt.*;
import java.util.*;
import java.awt.event.*;

public class DisplayFile extends Applet
{
TextArea text = new TextArea(5,2);

String FileName = "names.txt";
String newLine = System.getProperty("line.operator");

String[] surname = new String[20];
String[] firstname = new String[20];

StringTokenizer linesplit;
int nextElement=0;

public void init()
{
//BufferedReader input;
add(text);

try
{
displayFile();

}
catch(IOException error)
{
System.out.println("Can't open file");

}

}

public void displayFile() throws IOException
{
String path = getCodeBase().getFile();
BufferedReader input = new BufferedReader(
new FileReader("names.txt")); //path+getParameter("name"))

String inputLine = input.readLine();

while(inputLine != null && nextElement < firstname.length
&& nextElement < surname.length)
{

inputLine = input.readLine();
linesplit = new StringTokenizer(inputLine,",");
firstname[nextElement]=linesplit.nextToken();
surname[nextElement]=linesplit.nextToken();
text.append(surname + "," + firstname + newLine);
inputLine = input.readLine();
nextElement++;
}

change the following line

linesplit = new StringTokenizer(inputLine,",");

to

linesplit = new StringTokenizer(inputLine);
