How to assign default value to nullable types? Did nested nullable types are allowed..

Answer / msg

Here we have two ways to assign a default value.
1. By using Nullcoalsce(??) Operartor
2. by using getvalueordefault() Method.

ex: int? a= null;
int b = a ?? 10;
Or
int b =a.getvalueordefault(); //if null will return zero
or
int b = a. getvalueordefault(10);// if null will retrun 10
