What is the difference between Id(objString) and Id.valueOf(ObjString) in Salesforce?

Hi All,

What is the difference between Id(objString) and Id.valueOf(ObjString)?

I want to typecast the ObjString into the Id which way is better to do that?

Please give suggestion

Hi Mohit,

The first is casting. The second is calling a static method on the Id class.

One major advantage of the former is that it is more null safe.

Id idVal1 = (Id)null; // works
Id idVal2 = Id.valueOf(null); // blows up

First one is better.
