Java has had generics since 2004. 

However, they work with type erasure, so the <T> parameter information 
is not available at runtime directly from the code: i.e. generics really 
are type-safe macros. There is only one version of the compiled class 
generated, not a separate version for each <T>.  However, of course,  
types can be  ascertained by reflection on actual objects at runtime.  
And you can have wildcard references.
