What is the difference between IRobotApplication and RobotApplication

[HadiMoosavi]

Is there any difference between these two statements:

IRobotApplication robApp = new RobotApplication();

and 

RobotApplication robApp = new RobotApplication();

There seem to be many similar objects in RobotOM like: IRobotNodeSupportData and RobotNodeSupportData

my guess is this is a very basic programming question. Apologies.

hi @HadiMoosavi 

I for interface

An Interface is just a set of definition that you must implement in your Class inheriting that Interface.
