> C# generics are an (arguably improved) Java generics clone That depends on who you ask. My opinion is Java doesn’t have proper generics. In Java they’re just language-level syntactic sugar. Type system is broken i.e. type information is lost at compile time. This makes it hard to do functional-style programming in Java, that’s why other people made Scala. Performance is broken too, generic containers box everything into objects causing huge performance penalty for containers with value types.
