How does SObjectType.newSObject() works?

Question

From the documentation > SObjectType Class I see that we can instantiate a new sObject from the SObjectType class

Could you tell me how does the code below create a new Account regarding the required fields

Account newAcc = (Account)Account.sObjectType.newSObject();

Are the required fields ignored or are they filled with some default values ?

Answer 1

It will simply instantiate a new empty Account object.

Required fields only come into play when you perform the DML. You will have to set those.

This and the describe classes are useful when the object type in a method can vary and be identified during runtime.

Answer 2

From the documentation:

Constructs a new sObject of this type

Basically:

Account newAcc = (Account)Account.sObjectType.newSObject();

is same as:

Account newAcc = new Account();

It returns the instance of Object, you would need to populate additional fields yourself.

Here is an example to validate it:

Account objAccountobject = (Account)Account.sObjectType.newSObject();

Account objAccount = new Account();

System.debug('This would be true' + objAccountobject == objAccount);
