什么是清单类别 <Foo> 在Java中？

Question

Class c = List<Foo>.class

似乎不起作用。

Answer 1

There isn't one. In Java, concrete generic types have no exact runtime type representation. This is a consequence of the much-maligned type erasure . Effectively, this means that List<Foo> is the same runtime type as List<Bar> ; checking whether generic operations are legal happens at compile time, not runtime. Once you're in bytecode, they're all List , so saying something like List<X>.class is nonsensical to some degree.
