챌린지

Create a method for inserting accounts.

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 method must accept an incoming string as a parameter, which will be used to create the Account name
  • The method must insert the account into the system and then return the record
  • The method must also accept an empty string, catch the failed DML and then return null
