Scanning double with Scanner in Java from Console

I want to read a double number from standard input, but I always get this exception:

java.util.InputMismatchException

import java.util.Scanner;

public class ScanDouble {

    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        double d = scan.nextDouble();
        System.out.println("Double: " + d);

    }
}

If the input is integer it's okay, but when double, I get the exception.
