Tutorial: Object Oriented Programming

How to start

Check out the tutorial project from your group's repository.
Your solutions should be in the folder src.
You should never change any class in the tst folder.
The tasks are described in more detail in the mentioned files in the tst folder.
The first thing you should do is to run the tests¹⁾.
You will see that 11 of 14 tests are failing ²⁾. This means that we made assertions about the base code that are not true for the current implementation.
After you solved all tasks 12 of 14 tests should be successful ³⁾. If you decide to solve even the extra tasks everything should be green ⁴⁾ and there should be even more tests.

After you have solved this task, you should be able to understand and explain:

After you have solved this task, you should be able to understand and explain:

After you have solved this task, you should be able to understand and explain:

… how you can create subclasses.
… how class extension relates to interface implementation.
… how you can make use of inheritance to reuse common functionality.
See X1T03_PersonsStudentsProfessors in the package university in the tst folder.

After you have solved this task, you should be able to understand and explain:

… how to let your classes implement interfaces so that framework classes know what to expect from them.
… how to configure framework classes, so that you can extend their behavior without modifying them.
See X1T04_StudentTest in the package university in the tst folder.

If you're done with all the tasks above and you still have time and energy left you may want to work on …
