Add to your Playlist. The name of the class must be a valid C identifier name.

We don’t recommend creating object references such as this one that don’t refer corus an object because trying to access an object through such a reference will fail at run time.

An abstract class contains abstract methods that have a signature definition but no implementation. This reference refers to the new object but does not contain the object data itself. Please note that this closes all open sessions, so be sure to save your work before signing out. When the object is created, enough memory is allocated on the managed heap for that specific object, and the variable holds only a reference to the location of said object.
