CPF Validation on Android - Error in ArrayList

Navigation
2

I have this class to validate CPF field in android, however it is giving error in line: ArrayList<Separador> posicaoSeparadoresTexto(String mascara)

Here is the complete code: 

package com.mcavalini.lib;

import java.util.ArrayList;

public class Utils {

    public static int tamanhoMaximo(String mascara) {
        String novaString = removeCaracteresEspeciais(mascara);
        return novaString.length();
    }

    public static String removeCaracteresEspeciais(String str) {

        String[] caracteresEspeciais = {"\.", ",", "-", ":", "\(", "\)", "ª", "\|", "\\", "°", "\/"};

        for (int i = 0; i < caracteresEspeciais.length; i++) {
            str = str.replaceAll(caracteresEspeciais[i], "");
        }

        return str;
    }

    public static ArrayList<Separador> posicaoSeparadoresTexto(String mascara) {
        ArrayList<Separador> listaSeparadores = new ArrayList<Separador>();

        for (int i = 0; i < mascara.length(); i++) {
            if ( (mascara.substring(i, i+1).equals(new String(","))) ||
                 (mascara.substring(i, i+1).equals(new String("."))) ||
                 (mascara.substring(i, i+1).equals(new String("-"))) ||
                 (mascara.substring(i, i+1).equals(new String("/"))) ||
                 (mascara.substring(i, i+1).equals(new String("("))) ||
                 (mascara.substring(i, i+1).equals(new String(")")))) {
                listaSeparadores.add(new Separador(new Integer(i), mascara.substring(i, i+1)));
            }
        }

        return listaSeparadores;
    }

    public static String padString(String numero, int tamanhoMaximo, int tamanhoMascara, ArrayList<Separador> listaSeparadores) {
        String stringMascarada = "";
        boolean isPad = true;
        int indicePadString = 0;
        int indiceNumero = 0;
        int tamanhoNumero = numero.length();

        while (isPad) {
            for (Separador separador : listaSeparadores) {
                if (separador.getPosicao().intValue() == indicePadString) {
                    stringMascarada += separador.getCaracter();
                    indicePadString += 1;
                    break;
                }
            }

            if ((indiceNumero < tamanhoMaximo) && (indiceNumero < tamanhoNumero) ) {
                stringMascarada += numero.substring(indiceNumero, indiceNumero+1);
            } 

            indicePadString += 1;
            indiceNumero += 1;

            if (indiceNumero >= tamanhoNumero)
                isPad = false;
        }

        return stringMascarada;
    }

As already stated in the comments, the Separador class is missing. Let's create this class: 

public class Separador {
    private final Integer posicao;
    private final String caracter;

    public Separador(Integer posicao, String caracter) {
        this.posicao = posicao;
        this.caracter = caracter;
    }

    public Integer getPosicao() {
        return posicao;
    }

    public String getCaracter() {
        return caracter;
    }
}

And with that, your code should compile and work.

However, the code still has several other problems:

  • It does not use autoboxing and autounboxing properly, using new Integer(i) instead of just i and then using getPosicao().intValue() rather than simply getPosicao() .

  • The Separador class I put above was made to be compatible with the code, but could be better if posicao was int and not Integer and caracter was char and not% String , but for this you would have to change the Utils class.

  • Using new String(",") is unnecessary, just "," .

  • The presence of a class called ArrayList<Separador> full of static methods appears to be some deeper anti-pattern.

  • There must be other problems as well.
