This method takes name string parameter and makes a new Account. Then it tries to insert it, but if insert fails then it returns null. If insert succeeds, it will return that account object. 
public class AccountHandler {
public static Account insertNewAccount(String name) {
Account a = new Account();
a.Name = name;
try
{
insert a;
} catch (Exception e) {
return null;
}
return a;
}
}
NOTE:- your DML should be inside Try Catch.

Let us know if this will help you

Thanks

Hi Rica,

Please check the below code: 
public class AccountHandler {
    public static Account insertNewAccount(String n){
        if(n!=''){
            Account acc = new Account(Name=n);
            try{  
                insert acc;
               }
            catch(DmlException e){
                System.debug('Error Message is:'+e.getMessage());
            }
            return acc;
        }
        else
            return null;
    }
}


Hope this helps you!
Best Regards,

hi guys - i tried the code from both Deepthi and Amit, and got the following error from both ...

==========
Challenge Not yet complete... here's what's wrong: 
There was an unexpected error in your org which is preventing this assessment check from completing: System.NullPointerException: Attempt to de-reference a null object
==========

not sure what to do next - it's the "Attempt to de-reference a null object" that is really throwing me off
