类型不匹配：无法从 ArrayList 转换<bankKonto>布尔值

Question

public ArrayList<bankKonto> getKonto() {
    return konto;
}

And when i am in my main i add bankKontoObject to make a new one. Then i add 3 to my bankKonto

when i try to do a for loop

for(bankKonto b; bankKontoObject.getKonto() {


    System.out.println(b.getNummer()  + " " +b.getSaldo());

    }

Answer 1

for(bankKonto b : bankKontoObject.getKonto()) {
    System.out.println(b.getNummer()  + " " +b.getSaldo());
}

You missed a ')' at the end of 'getKonto' and the ';' should be a ':'
