Java OOP UML design

Design a lighting control system for a smart home. It should allow lights from different manufacturers and with different specifications to be controlled by the same app.

The app controls groups of lights. The groups are user-defined: the user can add a light to a group and remove a light from a group.

Some lights can dim smoothly while some are just on/off. Some lights may change colour.

Some lights can dim and change colour.

. Design an object-oriented application for the light system.

Draw a simple UML diagram showing the design of each class. You do not need to list getters/setters or constructors.

The application should have the following features.

The lights will have a method to change intensity and colour.

There will be a method to change the intensity and colour of all the lights in a group. All the lights in the group will be changed to the same intensity and colour.

Write pseudo-code or point-by-point English to clearly describe how these two methods work.
