denis panou Small help in etuding (Manipulating Records with DML)
Hi all.Sorry for questions but i really dont understand what i do wrong
i try finish Apex Basic module
and stop in third episode
thats text of challenge
To pass this challenge, create an Apex class that inserts a new account named after an incoming parameter. If the account is successfully inserted, the method should return the account record. If a DML exception occurs, the method should return null.The Apex class must be called 'AccountHandler' and be in the public scope.
The Apex class must have a public static method called 'insertNewAccount'.
The 'insertNewAccount' method must accept an incoming string as a parameter, name the account after the parameter, insert it into the system and then return the account record.
The 'insertNewAccount' method must also accept an empty string, catch the failed DML and return null.
that's my code
public class AccountHandler {
public static String insertNewAccount(String str) {
try {
Account acct = new Account(Name=str);
insert acct;
} catch (DmlException e) {
System.debug('A DML exception has occurred: ' + e.getMessage());
return null;
}
return str;
}
}
in my logic it must works, but it failed and i don't know why, please help me, what's wrong in my code?

but you are returning str that is just a account name
2) it say The 'insertNewAccount' method must also accept an empty string, so i belive you need to put a check on the top that if str is blank or null it return null on the 1st place
you can try this
public class AccountHandler {
public static Account insertNewAccount(String str) {
if(str 1= null)
{
try {
Account acct = new Account(Name=str);
insert acct;
return acct;
} catch (DmlException e) {
System.debug('A DML exception has occurred: ' + e.getMessage());
return null;
}
}
return null;
}
}
public class AccountHandler {
public static Account insertNewAccount (String accName){
if(accName!=''){
try{
Account a = new Account(Name=accName);
insert a;
System.debug('Account created');
return a;
} catch(Exception e){
System.Debug('Account not created');
return null;
}
} else {
return null;
}
}
}
