Can you explain the Observer design pattern in C++ and Java?
Sure! The Observer pattern is a behavioral design pattern that allows an object, known as the subject, to maintain a list of its dependents, called observers, and notify them of any state changes.
How is it implemented in C++?
In C++, you typically use a combination of classes and interfaces. The subject class maintains a list of observers and provides methods to attach, detach, and notify them.
And how does it differ in Java?
In Java, the Observer pattern is often implemented using the built-in Observer and Observable classes. Java provides a more straightforward way to manage the observer list and notifications.
Can you give me a simple code example for both languages?
Certainly! In C++, you might have a Subject class with methods to add and notify observers, while in Java, you can extend the Observable class and override the notifyObservers method.
