What are the differences between command pattern and other design patterns?

The command pattern encapsulates a request as an object, allowing for parameterization and queuing of requests. Other patterns, like the observer or strategy patterns, focus on different aspects of object interaction.

Can you give me an example of the command pattern in action?

Sure! Imagine a remote control for a TV. Each button on the remote can be a command object that encapsulates the action of turning the TV on or off, changing channels, etc.

How does the command pattern improve code maintainability?

It separates the object that invokes the operation from the one that knows how to perform it, making it easier to modify or extend functionality without changing existing code.

What are some other design patterns I should know about?

Some important design patterns include the singleton, factory, observer, and strategy patterns. Each serves a unique purpose in software design.
