Quote on Java Generics


From some guy on Hacker News:

…to add insult to injury, its static type system is very weak. A combination of type erasure, a failure to unify arrays with generic types, and poor type checking in the reflection system means that Java’s static typing doesn’t give you particularly much help with writing well-factored code compared to most other modern high-level languages. Speaking of generics, the compiler’s handling of generics often leaves me feeling like I’m talking to the police station receptionist from Twin Peaks. Every time I have to explicitly pass “Foo.class” as an explicit argument when the compiler should already have all the information it needs to know what type of result I expect, I cry a little inside. Long story short, if I could name a type system to be the poster child for useless bureaucratic work for the sake of work, it would be Java’s.
