What are some real-world examples of state patterns in software design?

State patterns are used in various applications. For instance, in a video game, a character's behavior can change based on its state, like 'Idle', 'Running', or 'Attacking'. Each state has its own set of rules and actions.

Can you give me another example?

Sure! In a media player application, the player can be in different states such as 'Playing', 'Paused', or 'Stopped'. Each state dictates what actions are available to the user.

How does the state pattern improve code maintainability?

The state pattern encapsulates state-specific behavior, making it easier to manage and extend. It reduces conditional logic and promotes cleaner code.

Are there any drawbacks to using the state pattern?

Yes, one drawback is that it can lead to an increase in the number of classes, which might complicate the design if not managed properly.
