branje iz fajla v javi

Evo primerček:

import java.io.*;

public class TextReaderApp{
public static void main(String[] args) throws IOException{
File data = new File("example.txt");
if (data.exists()){
BufferedReader in = new BufferedReader(
new FileReader(data));
String line = in.readLine();
while(line != null){
System.out.println(line);
line = in.readLine();
}
in.close();
}
else
System.out.println("File not found - example.txt");
}
}

hi!
ja tale programcek bere fajl, ampak takega sem tudi sam ze napisal;)
kar mi dela tezave je, da bi odstranil locila, kajti vse to rabim za analizo besedila. torej bi moral nekako delati s tokenizerjem in delimitersi, pa tega ne znam vkljucit v ta program;(

import java.io.*;
import java.util.StringTokenizer;

public class TextReaderApp{
public static void main(String[] args) throws IOException{
File data = new File("krpan.txt");
if (data.exists()){
BufferedReader in = new BufferedReader(
new FileReader(data));

String line = in.readLine();
StringTokenizer tok=new StringTokenizer(line, " ,.");

while(line != null){ //po vrstici
while (tok.hasMoreTokens()) { //po besedah

System.out.println(tok.nextToken());
// tok.nextToken();
}

line = in.readLine();
}
in.close();
}
else
System.out.println("File not found - example.txt");
}
}

naredil sem 2 zanki, taprva tece po vrsticah, ta druga pa po besedah znotraj vrstice(tokenih).
tezava je v tem, da ko pride do nove vrstice v fajlu, program neha delat.
to pa zato ker ne zna(m) narediti, kako naj prebere/skoci v novo vrstico?
kakrsnakoli ideja?!
