NumberFormatException when converting Integer String in Java

Question

I declare this variable:

private String numCarteBancaireValide=String.valueOf(((Integer.parseInt(Config.NUM_CARTE_BANCAIRE_VALIDE)   ) + (Integer.parseInt(\"         


        

Answer 1

Integer.parseInt will attempt to parse an integer from a String.

Your "4111111111111111" String does not represent an valid Java integer type, as its value would be > Integer.MAX_VALUE.

Use Long.parseLong instead.
