Lesson 9
No Object is an Island
Chapter 3: Refactor your robot!
Summary
You have now defined a RobotFactory
class. This class is used to create multiple new Robot
s with randomly initialised names, positions and locations.
In this style of programming, you are delegating the responsibility of creating and initialising class instances to a Factory
class. This follows the Single Responsibility Principle, which basically says that each class should only be responsible for one aspect of the program, rather than being overloaded with too many tasks. This is a good way of thinking when designing your classes. It also helps to imagine each class focussing on doing its own thing, and at the same time collaborating with other classes to achieve a larger goal.
There are potentially more objects that can be created for the robot project, each with its own responsibility. We will come back to do this later!
