BE1 - Behavioral Design Pattern

Which behavioral design pattern allows objects to be notified and updated by a subject when its state changes?

• Strategy Pattern
• Observer Pattern
• Template Method Pattern
• Command Pattern

Which behavioral design pattern enables the selection of an algorithm at runtime?

• Strategy Pattern
• State Pattern
• Mediator Pattern
• Chain of Responsibility Pattern

Which behavioral design pattern defines the skeleton of an algorithm, allowing subclasses to redefine certain steps without changing the algorithm's structure?

• Template Method Pattern
• Iterator Pattern
• Command Pattern
• Visitor Pattern

Which behavioral design pattern allows an object to alter its behavior when its internal state changes?

• Memento Pattern
• State Pattern
• Mediator Pattern
• Chain of Responsibility Pattern

Which behavioral design pattern encapsulates a request as an object, thereby allowing clients to parameterize clients with different requests?

• Observer Pattern
• Strategy Pattern
• Command Pattern
• Visitor Pattern

Which behavioral design pattern provides a way to access the elements of an aggregate object sequentially without exposing its underlying representation?

• Iterator Pattern
• Mediator Pattern
• Chain of Responsibility Pattern
• Visitor Pattern

Which behavioral design pattern defines an object that encapsulates how a set of objects interact, promoting loose coupling between them?

• Strategy Pattern
• Mediator Pattern
• Memento Pattern
• Visitor Pattern

Which behavioral design pattern allows an object to pass a request along a chain of potential handlers until one of them handles the request?

• Template Method Pattern
• State Pattern
• Command Pattern
• Chain of Responsibility Pattern

Which behavioral design pattern separates an algorithm from the object structure it operates on, allowing new operations to be added without modifying the objects?

• Visitor Pattern
• Observer Pattern
• Strategy Pattern
• Memento Pattern

Which behavioral design pattern allows an object to capture and externalize its internal state so that it can be restored later?

• State Pattern
• Command Pattern
• Memento Pattern
• Visitor Pattern
