Firstly, before you subclass an object, you should ask yourself “do I need to do this?”. Subclassing is a more complex way of interacting and extending the functionality of other classes, so you should make sure that what you are trying to achieve cannot easily be achieved through another, simpler method, such as delegation, notifications … Read more
