Exam CRT-450 topic 1 question 27 discussion

abc is correct

Map<Id, Account> accountMap = new Map<Id, Account>([Select id, Name from Account]); for(Id accountId: accountMap.keySet()){ System.debug('accountId->A'+ accountId); } for(Account accountRecord: accountMap.values()){ System.debug('accountRecord->B'+ accountRecord); } for(Integer i= 0; i<accountMap.size(); i++){ System.debug('i ->C'+ i); } for(Id accountId: accountMap){ System.debug('accountId->D'+ accountId); } for(Account accountRecord: accountMap.keySet()){ System.debug('accountRecord->E'+ accountRecord); }

explain how c is correct with code

abc correct

choices: A. for (ID accountID : accountMap.keySet()) {…} B. for (Account accountRecord : accountMap.values()) {…} C. for (Integer i=0; I < accountMap.size(); i++) {…} D. for (ID accountID : accountMap) {…} E. for (Account accountRecord : accountMap.keySet()) {…}

I see what happend here, the person who creates this question, just cheked those staments, and only work for ABC, so in that context DE are worng, But you are asumming that some code is missing on those (DE)

E cannot be the right answer as Keyset contains Id so in order to loop it needs ID For(ID thisloop: Map.keyset()) is correct For(Account acc: Map.keyset()) is incorrect

instead of B, it should be E.
