What are the differences between Java Generics and C++ Templates?

What are the differences between Java Generics and C++ Templates?

Java Generics and C++ Templates are both used for code reusability, but they have key differences. Generics are implemented at the compile-time in Java, while C++ Templates are more powerful and allow for type manipulation at compile-time and run-time.

Can you explain how type erasure works in Java Generics?

Sure! Type erasure in Java Generics means that the generic type information is removed during compilation. This allows for backward compatibility with older versions of Java that do not support generics.

What are some advantages of using C++ Templates over Java Generics?

C++ Templates offer more flexibility, such as template specialization and the ability to work with non-type parameters. This allows for more complex and optimized code.

Are there any performance differences between the two?

Yes, C++ Templates can lead to better performance due to compile-time optimizations, while Java Generics may introduce some overhead due to type erasure.
