Reading a txt file

[diegosened]

Hello... i'm a beginner with java and so i new your help!
i've just tried to create a java program which should read a txt file and then shows the content... but i don't know the reason why it doesn't work! could you check it? when the program works i don't see an error report, but it doesn't show me anythink!

This is the program

import java.io.;
import java.util.;


class LeggiFile
{
// costruttore
public LeggiFile() {}

public void leggeToken()
{
FileReader f = null;
BufferedReader fIN = null;
String s;


try
{
f = new FileReader("diego.txt");
fIN = new BufferedReader(f);
}
catch (IOException e)
{
System.out.println("Errore nell'apertura del file");
System.exit(1);
}

try
{

s = fIN.readLine();
while (s != null)
{

// operazioni sulla stringa s

s = fIN.readLine();
}
}

catch (IOException e)
{
System.out.println("Errore nella lettura del file.");
System.exit(1);
}

try
{
f.close();
}
catch (IOException e)
{
System.out.println("Errore nella chiusura del file.");
System.exit(1);
}
}


public static void main(String args[])
{
LeggiFile a = new LeggiFile();
a.leggeToken();
}
}

Does this compile? I ask because the import statements look a little weird.

Anyway in your while loop you read the file but you don't do anything with the strings that are read. Try:

while (s != null)
{
        // operazioni sulla stringa s
    System.out.println(s);

    s = fIN.readLine();
}

Two things:
1 — add an asterisk to the end of your import statements

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

2 — write out each line to the console:

        try
        {
            s = fIN.readLine();
            while (s != null)
            {
                // operazioni sulla stringa s
                [b]System.out.println(s);[/b]
                s = fIN.readLine();
            }
        }

thanks!!! i made it!!!!
i wanna ask you another think..
my goal now is that each word (contained in the txt file) should be seen line per line.
For example
txt file: i do not know java

i have to see in the video:
i
do
know
java

could i do this?
sorry for my bad grammar!

this is the program

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

  class FileRead  {
    
     public static void main(String args[]) {
        
        FileRead f = new FileRead();
        f.readMyFile();
     }

        public void readMyFile() {
            FileReader f = null;
            BufferedReader fIN = null;
            String s;

            try {
             
               f = new FileReader("diego.txt");
               fIN = new BufferedReader(f);
               s = fIN.readLine();

               while(s != null) {
                    System.out.println(s);
                    s = fIN.readLine();
               }
          
             }
             
             catch (IOException e) {
                 System.out.println("Errore nella lettura del file");
             }

             finally {
                
                 if(fIN != null) {
                    try {
                        fIN.close();
                    }
                    catch (IOException e) {
                       System.out.println("Errore nella chiusura del file.");
                    }
}
}
}
}
