Null check for Map Value sObject

Question

I'm looking for the logical syntax to determine if a sobject is empty.

ACCOUNT oRecord = new ACCOUNT();
ACCOUNT oRecord1 = new ACCOUNT();

Map<Id,ACCOUNT> mCommPref = new Map<Id,ACCOUNT>();
mCommPref.put('a2r1h000000hCPMAA2', oRecord);
oRecord1 = mCommPref.get('a2r1h000000hCPMAA2'); 

system.debug('oRecord111 -->' + oRecord1);
system.debug('oRecord1 -->' + oRecord1 == null);

but the oRecord1 == null return False, Need to Return as true when there is no value in the sobject. Can you help me on this

Tried by adding Empty Object as below

ACCOUNT empty = new ACCOUNT();
system.debug('oRecord1 -->' + oRecord1 == empty);

the above code getting this error

Comparison arguments must be compatible types: String, Account

Answer 1

oRecord1 == null returns false because there is an instantiated Account.

Seeing as the Accounts have Ids, you should be able to use:

oRecord1?.Id == null

Answer 2

You're confusing "null" with "empty." An empty object is an object with no values populated, while a null object is one that doesn't exist. If you want to check if it's an "empty" account, you can:

system.debug('oRecord1 -->' + (oRecord1 == new Account()));

The == operator checks all the populated values in two sobjects to see if they're equal.
