Command Design Pattern

Why we use this pattern

Assume we have designed a framework that has a button that has a custom-designed button. This framework is reused in several projects. In one project it is used to add a customer and in another project, it is used to add a product to a cart.
The button action should be independent and depend on how the clients that use it. meaning the client will determine the implementation of the click action.

Define the button class -> Have a method for click action.
Define the interface that has an abstract method that can be used to delegate the work from Button to the implementation that uses the framework
We need to define an implementation for the command by implementing the interface. In this class, we need to have a constructor that sets the reference of the implementation.
In the overridden method of the implementation, using the reference of the implementation, we need to call the function that contains the logic
Finally, define create the Implementation object -> then create the command object that takes the reference of implementation object in the constructor -> then pass the command to the button class -> the with button reference call the click
