Txt Files

[eldiablo3000]

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

you can use System.out.println() , System.out.print(), System.out.printf() ......

System.out.print("uvas.txt")

will this show on screen the content of the file?

example:
uvas.txt
content:"
(trincadeira douro boa 100)
"

you have already done this

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

those variables contains the contents from the file already. All you have to do is print them out

but in main i did

System.out.println("Uvas.txt");

and appear "Uvas.txt" not the content

but in main i did

System.out.println("Uvas.txt");

and appear "Uvas.txt" not the content

that only prints the strin "Uvas.txt". you are already using a Scanner on Uvas.txt. so the variables that store the scanner inputs ( the ones i mentioned) are the data you need.

so how can i print the variables stored by scanner?
