So, I think the main question is how to format your double with a Euro sign. For this, you can simply set the currency NumberFormat should use:

NumberFormat format = NumberFormat.getCurrencyInstance();
Currency currency = Currency.getInstance("EUR");
format.setCurrency(currency);

System.out.println(format.format(40.27));

Output:

€40.27

This method only adds the € sign, but does not change the decimal point or anything else. Alternatively, you can also use the format of a specific country. For example France:

NumberFormat france = NumberFormat.getCurrencyInstance(Locale.FRANCE);
System.out.println(france.format(40.27));

Output:

40,27 €
