|Ans. When we create reference for primitive type, it's memory is allocated. So even if we don't assign any value to it, the default value is initialized.|
int x; // default value 0 initialized
But for object references, it's different as references hold nothing till an object is assigned.
Object obj; // contains null
So all primitive types when declared , contains their respective default values on the basis of their type whereas all wrapper class References contains null irrespective of their types.
