The diagram below shows the superclass train journey as having two derived classes namely a freight train and a passenger train. Uml is inherently object oriented modeling language and uses inheritance as one of its fundamental concepts while no uml specification provides appropriate details of how they actually define or interpret inheritance in uml. Both freight and passenger class have the data and methods of train journey and they also have their own unique data and methods. I ve made this sketch but i m not sure if it is correct.
