What is the command pattern in programming?
The command pattern is a behavioral design pattern that turns a request into a stand-alone object. This allows for parameterization of clients with queues, requests, and operations.
Can you give me an example of the command pattern in Java?
Sure! In Java, you can create a Command interface with an execute method, then implement this interface in concrete command classes. You can also have an invoker class that calls the command.
How does the command pattern differ in Python?
In Python, the command pattern can be implemented using functions as first-class objects. You can define command functions and store them in a list or dictionary for execution.
What are the benefits of using the command pattern?
The command pattern provides several benefits, including decoupling the sender and receiver, supporting undoable operations, and enabling logging of requests.
