Java泛型的参数只可以代表类，不能代表个别对象。

---

由于Java泛型的类型参数之实际类型在编译时会被消除，所以无法在运行时得知其类型参数的类型。

 > In Java, generics are only checked at compile time for type correctness. The generic type information is then removed via a process called type erasure, to maintain compatibility with old JVM implementations, making it unavailable at runtime. 

Java编译程序在编译泛型时会自动加入类型转换的编码
