What are the differences between C++ templates and Java generics?

What are the differences between C++ templates and Java generics?

C++ templates are a compile-time feature that allows for type-safe generic programming, while Java generics are implemented through type erasure at runtime.

Can you explain what type erasure means in Java generics?

Type erasure is the process by which the Java compiler removes all generic type information during compilation, replacing it with the raw types.

Are there any performance implications of using Java generics?

Yes, since Java generics use type erasure, there can be some performance overhead due to casting and the need for runtime checks.

How do templates in C++ handle type safety?

C++ templates provide type safety at compile time, allowing the compiler to catch type errors before the code is run.
