I’m treating a file .csv with a id, value (1,214.45) and I need to format a final sum of these values with only two boxes after the comma.

I developed the following code snippet:

`DecimalFormat df = new DecimalFormat("0.##");
    for(Integer i : filiais) {
        Double soma = 0.0;
        int contador = 0;
        for(String s : list) {
            String[] arr = new String[2];
            arr = s.split(",");
            if (arr[0].equals(i.toString())) {
                soma += Double.parseDouble(arr[1]);
                contador++;
            }
        }
        String aux = df.format(soma);
        somaFiliais.add(Double.parseDouble(aux));
        contadorFiliais.add(contador);
    }`

I have the following mistake:

Exception in thread "main" java.lang.NumberFormatException: For input string: "53010,77"

    To use the Double.parseDouble you need to replace the comma with the point (in the variable aux)

  • direct in number? do not know how to do...

  • remembered, used the . replaceAll, thank you very much Valdeir!!

  • It was solved with the replaceAll following @Valdeirpsr’s suggestion, take advantage and put as a response so you can help future readers.

  • @A.Fernando, have a special reason to use Double? In general it is better to use Bigdecimal.
