What is the Factory Design Pattern in C++ and Java?

Can you explain the Factory Design Pattern in C++ and Java?

Sure! The Factory Design Pattern is a creational pattern that provides an interface for creating objects in a superclass, but allows subclasses to alter the type of objects that will be created.

How does it differ between C++ and Java?

In C++, you typically use pointers and dynamic memory allocation, while in Java, you rely on references and garbage collection. The syntax and implementation details vary, but the core concept remains the same.

Can you give me a code example in both languages?

Absolutely! In C++, you might have a ShapeFactory that creates Circle or Square objects. In Java, you would have a similar ShapeFactory class that returns instances of Circle or Square based on input.

What are the benefits of using the Factory Design Pattern?

The main benefits include improved code maintainability, the ability to introduce new types without modifying existing code, and better separation of concerns.
