Exception in thread "main" java.util.InputMismatchException "double" input error

First of all, I've read the many threads about this error, but none solved my problem.

Here's my code:

import java.util.Scanner;

public class Programa1 {

    public static void main(String[] args) {
        Scanner s = new Scanner(System.in);

        double strana_a, strana_b, strana_c;
        strana_a = s.nextDouble();
        //strana_b = s.nextDouble();
        //strana_c = s.nextDouble();

        System.out.println(strana_a);

        s.close();
    }

}

When I type 8.0 for example, it shows me this error, what am I doing wrong?

As told in my previous comment (I'd like to convert it into an answer), it's a problem of the Locale (from the variables' names, it seems that you're Italian). Use comma instead as point (8,5, and not 8.5), or initialize the Scanner using the proper Locale for point, like this:

Scanner scanner = new Scanner(System.in).useLocale(Locale.US);
