Thread: 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

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.
