从方法返回泛型

Question

How I can return generic type from method? I wrote like this, but it dont work:

private static JsArray<T> convertListToJsArray(Collection<T> list)

I need to get Collection as parameter, and return parametrized JsArray.

Answer 1

您必须在返回类型前面指定type参数：

private static <T> JsArray<T> convertListToJsArray(Collection<T> list) {}

Answer 2

You need to declare the T type. This should work (notice the extra <T> before your return type):

private static <T> JsArray<T> convertListToJsArray(Collection<T> list)
