OOPS based question of University

Define a set of classes and methods to model these entities:
- a Light that you can turn on and off
- a Light that you can turn on and off and also set to a specific light level e.g. 50% brightness.
- a Scene which contains a number of Lights, with a level specified for each Light
o a Scene can be turned on or off
o Lights can be in multiple Scenes
o A Light is only turned off if all Scenes that it is part of are off

In our scenario we have 2 Scenes (A and B).
Scene A
- Lights 1 (on), 2 (on), and 3 (50%).

Scene B
- Lights 3 (70%), 4 (on), and 5 (on)

Write some client code that will create the objects to model our 2 Scenes, turn on both scenes, then turn off Scene B. Please show the implementation that will allow Light 3 to stay on after Scene B is turned off.



Sample answer :

Scene pSceneA, pSceneB;
pSceneA = new Scene
pSceneB = new Scene

pSceneA.AddLight( new Light(“1”), 100 )
pSceneA.AddLight( new Light(“2”), 100 )
pSceneA.AddLight( new Light(“3”), 50 )

pSceneB.AddLight( new Light(“3”), 70 )
pSceneB.AddLight( new Light(“4”), 100 )
pSceneB.AddLight( new Light(“5”), 100 )


pSceneA.On()
pSceneB.On()
pSceneB.Off()



any solution please!!!!
