Refactoring useless Method away

Real-life challenge, convert a bunch of ifs to a switch statement

Start file

if (isTyp(YBD.Typ_GEBAEUDE, currentTyp)) {
        immobilienItem.setGebaeudeNr(currentItem.getGebaeudeNr());
}
if (isTyp(YBD.Typ_OBJEKT, currentTyp)) {
        immobilienItem.setObjektNr(currentItem.getObjektNr());
}
if (isTyp(YBD.Typ_ETAGE, currentTyp)) {
        immobilienItem.setEtageNr(currentItem.getEtageNr());
}
if (isTyp(YBD.Typ_IMMOBILIE, currentTyp)) {
        immobilienItem.setImmobilieNr(currentItem.getImmobilieNr());
}
if (isTyp(YBD.Typ_HAUS, currentTyp)) {
        immobilienItem.setHausNr(currentItem.getHausNr());
}

End file

switch (currentTyp) {
        case YBD.Typ_GEBAEUDE:
                immobilienItem.setGebaeudeNr(currentItem.getGebaeudeNr());
                break;
        case YBD.Typ_OBJEKT:
                immobilienItem.setObjektNr(currentItem.getObjektNr());
                break;
        case YBD.Typ_ETAGE:
                immobilienItem.setEtageNr(currentItem.getEtageNr());
                break;
        case YBD.Typ_IMMOBILIE:
                immobilienItem.setImmobilieNr(currentItem.getImmobilieNr());
                break;
        case YBD.Typ_HAUS:
                immobilienItem.setHausNr(currentItem.getHausNr());
                break;
}
