Description

Problems for exercises and homework for the “C# OOP” course @ SoftUni”.
1. Stream Progress Info
Refactor the code for this task, so that Stream Progress Info can work with different kinds of Streams. First make sure it works with Music too. Refactor the code, so in the future if a new kind of stream is introduced, you will need to just import one new class with BytesSent and Length getters in it.
2. Graphic Editor
Refactor the code for this task, so that Graphic Editor can draw all kinds of shapes without checking what kind is the concrete shape. In the future, new shapes will be added to the system, so prepare the system for those moments. When you add a new shape, you should just add a new class and nothing more.
3. Detail Printer
Refactor the code for this task, so that Detail Printer doesn’t need to ask what kind of an employee is passed to it. Detail Printer needs to just print details for all kinds of employees. When a new kind of employee is added, you will only need to add a new class and nothing more.
4. Recharge
You are given a library with the following classes:
• Worker implements ISleeper
• Employee inherits Worker
• Robot inherits Worker
• RechargeStation
If you inspect the code, you can see that some of the classes have methods that they can’t use (throw UnsupportedOpperationException), which is a clear indication that the code should be refactored.
Refactor the structure, so that it conforms to the Interface Segregation principle.
Hints
Make the Robot extend Worker and at the same time implement Rechargeable.
