Need help at practice

Hello there! I need help on the practice exercise 46.2 I am stuck solving it for one week. Today I decided I "cheat" by just writing the output in the main class and it worked. But I want to solve it the right way. Even with the help of the solved code I didn't figure it out.(It always says "no output ") So can please some explain interfaces and abstract classes and send the solution for 46.2? I would really appreciate it!

java abstract-classes interfaces
