Usage

From source file:Main.java

        BufferedReader br = new BufferedReader(isr);
        String s = br.readLine();
        DecimalFormat df = new DecimalFormat();
        Number n = df.parse(s);
        numberFromConsole = n.doubleValue();
    } catch (IOException e) {
        numberFromConsole = 0;
    } catch (ParseException e) {
        numberFromConsole = 0;
    }
