Difficulty in Extending:?

• The Singleton Pattern makes it harder to extend or inherit the class due to its

static nature.

Conclusion:

The Singleton Pattern is a powerful tool for ensuring that a class has only one instance and

provides a global access point to that instance. It's useful for managing shared resources

like configuration settings, logging, or caching. However, care should be taken when using it,

especially in multi-threaded applications, and consideration should be given to the

challenges in testing and extending the class.

State Pattern: Allowing Object Behavior to Change Based on Its State

Definition:

The State Pattern allows an object to change its behavior when its internal state changes.

The object will appear to change its class. It's used when an object's behavior is dependent

on its state and the object needs to behave differently in different states without using

complex conditionals.

Use Case:

The State Pattern is useful in scenarios where an object's behavior is conditional on its

state. A typical use case is a traffic light system where the behavior (light change) varies

based on the current state (Red, Green, Yellow).
