Create instance of generic class by reflection

Question

Is there any way to use reflection to create an instance of a generic class.

For example, how to create an instance of PriorityQueue<Integer> using reflection such as Class or Type, instead of call its constructor.

Answer 1

您始终可以将原始类型转换为泛型类型/从泛型类型转换。

PriorityQueue<Integer> queue = (PriorityQueue<Integer>) PriorityQueue.class.newInstance();
