Hello guys, my code makes a mistake and talks "this method should return a string type result". The error is in String situacao().... Could someone help me how to fix this please ?

  • Your if is weird. First you test if icmsResidencial() <= ICMS1 (up here, ok). But then you do else if(icmsResidencial() > ICMS1 && icmsResidencial() == ICMS1) - that is, if icmsResidencial is larger and equal to ICMS1 (There’s no way he’s bigger and equal at the same time, so you’ll never get into that if). And as the first if already tests whether it is less or equal, the only alternative that remains for the else is that he’s bigger, so that’s else if doesn’t make sense.

Your method must return a string. It is printing in the method itself instead of returning the text as a result.

String situacao( ) {
    String retorno;

    if  (icmsResidencial() <= ICMS1) {
        retorno = "Você esta Isenta de imposto ICMS";
    }else if(icmsResidencial() > ICMS1 && icmsResidencial() == ICMS1) {
        retorno = "12% de ICMS";
    }else {
        retorno = "25% de ICMS";
    }       

    return retorno;
}
