Teil 4 von 9 konventionelle Methode A tutorial dialogue Step 1: Teacher to Student A class my inherit features form more than one superclass. A class with more than one superclass ist called a join class. This is known as multiple inheritance.
Teil 4 von 9 konventionelle Methode A tutorial dialogue Step 2: Student to Teacher A join class can inherit features from more than one superclass.
Teil 4 von 9 konventionelle Methode Land Vehicle Water Vehicle Car Amphibious Vehicle Boat Step 3: Teacher to Student Vehicle The land vehicle and the water vehicle are overlapping sub-classes of the superclass vehicle. The overlapping sub-class is indicated by the solid triangle. They are overlapping sub-classes due to the fact that some vehicles can travel both on land and on water. Amphibious vehicle is the join class of land and water vehicles as it can travel both on land and on water. It iherits some features from both the land vehicle and water vehicle classes. The hollow triangle indicates disjoint sub-classes. For example, car and amphibious vehicle are disjoint sub-classes.
Teil 4 von 9 konventionelle Methode Step 4: Student to Teacher Ahh! Now I understand... The amphibious vehicle inherits properties from land as well as water vehicles and is the join class for super-classes, land vehicle and water vehicle. Step 5 + 6: Teacher to Student Okay... Let us consider another example, in our University. Consider our University wich comprises of different people. It includes faculty members, students and tutors. Can you draw an object model showing the class hierarchy of these different objects?
Teil 4 von 9 konventionelle Methode Student Faculty Tutor Step 7: Student to Teacher University Step 8: Teacher to Student Okay, let us look at the problem in this way...You are a second year undergraduate student here in RMIT‘s Computer Science Department. I am undertaking my Masters degree at RMIT, which makes me a student, and since I am teching you I am also a faculty member. Can you modify your object model to represent this situation?
