How do structural design patterns differ between C++ and Java?

How do structural design patterns differ between C++ and Java?

Structural design patterns focus on how classes and objects are composed to form larger structures. In C++, you often use pointers and references, while Java uses references and interfaces. This leads to differences in implementation.

Can you give me examples of specific patterns?

Sure! Common structural patterns include Adapter, Composite, and Decorator. In C++, you might use templates for the Adapter pattern, while in Java, you would typically use interfaces.

What about performance differences?

Performance can vary due to language features. C++ allows for more low-level memory management, which can lead to faster execution, while Java's garbage collection can introduce overhead.

Are there any patterns that are easier to implement in one language over the other?

Yes, some patterns like Proxy can be easier in Java due to built-in support for dynamic proxies, while C++ may require more boilerplate code.
