Quick quetion about Java Generic and Reflection

[gbb21]

For a generic class, for example, List<T>, how can I get the "Class" object ?

For raw type List, I can get Class<List> by calling List.class; however, I cannot call List<T>.class to get Class<List<T>> object.

The motivation that I want to get Class<List<T>> is for the follow function call.

List<T> list = create(Class<List<T>> c);


thanks for your help, in advance .

create(Class<List<T>> c);
这个方法接收一个普通的Class对象就可以了，返回一个List可以直接赋值给List<T> list

If I call "create" function with List.class as argument, compiler will give me warning .....(saying something about raw type ....)

[ldq67123]

if the list is not empty and the Class<T> is a POJO,your can test the type of any element in the list
if not ,or the Class<T> is just a abstract class,your have to test every element to get its type
does anyone have a better solution?

你应该说nobody！

你该看看泛型擦除，运行时是无法得到类型参数的信息的。而且，List类只有一个，不是说有多少种类型参数就会有多少个List类，所以也没有List<T>.class这种东西，只能是List.class。
