What are the differences between interfaces in C++ and Java?

What are the differences between interfaces in C++ and Java?

In Java, interfaces are a core part of the language, allowing multiple inheritance. C++ uses abstract classes for similar functionality.

Can you explain how multiple inheritance works in Java interfaces?

In Java, a class can implement multiple interfaces, allowing it to inherit behavior from multiple sources without ambiguity.

What about C++? How does it handle multiple inheritance?

C++ allows multiple inheritance directly, but it can lead to ambiguity if not managed properly, often requiring virtual inheritance.

Are there any performance differences between using interfaces in C++ and Java?

Yes, performance can vary; C++ interfaces (abstract classes) are generally faster due to less overhead compared to Java's dynamic method dispatch.
