Could someone tell me if a NULL object occupies memory?
I have the following Scenario, I have a class
C , and class
C is inside the class
A , then how would the memory be in these 3 scenarios ?
1. ClassC C = null; 2. ClassA A = new ClassA() A.B = new ClassB(); A.C = null; 3. ClassA A = null;
In those 3 scenarios, how is memory allocation? if it is NULL, does it not use memory? or how those scenarios are handled internally.
