Are there objects that dont exist?


Question


Are there objects that dont exist?


Answer


This is just my take from a programmers point of view. If an object does not exist, it is null object. This means the definition for the object is there, but there is no instance of the object in existence. Let us say that we have an idea for widget X. We have a definition for it, but until it is built, it does not exist. However, once it comes into the mind as a physical thing, then it exists.
