    Exclamation TXT files


    Hello everyone,

    I Would like to ask you 2 simple questions that I cannot answer by myself.


    1 I need to "import" a txt file to memory and then print it on screen.

    I have already done the first part. I is correct?

    2 How can I print the file to the screen?

    private static void leInfo(){
    LineNumberReader ficheiro;
    try {
    ficheiro = new LineNumberReader(new FileReader("Uvas.txt"));
    Scanner sc = new Scanner(ficheiro);

    while(sc.hasNext()){
    String nome =sc.next();
    Regiao reg=Regiao.valueOf(sc.next());
    Qualidade qual=Qualidade.valueOf(sc.next());
    int quantidade=sc.nextInt();


    }

    } catch (Exception e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
    }
    }

    Thank You very much

    Default Re: TXT files

    A way you could do it is:

    Use a FileReader to read the file:
    FileReader fr = new FileReader("Uvas.txt");
    then you could use a BufferedReader to read the text on the file:
    BufferedReader br = new BufferedReader(fr);

    Then you could use a try-catch statement to read everything and print it out:
     try {
    String text;  //you make a new String for text
                            while ((text = br.readLine()) != null) {
                                System.out.println(text);
                            }
                        } catch (IOException ex) {
                          System.out.println("this doesn't work because: " + ex);
     
                        }
                    } catch (FileNotFoundException ex) {
                        System.out.println(" not found :" + ex);
                    }

    Again, this isn't the way you do it. but it might help.
