Can we call a method by inferring a type ?

Question

Hi,
Pardon my ignorance. Why doesn't type inference help in writing code like this ?
<code>
public class TypeInferredMethodCall {
private interface Base {
     public void x();
private static class Derived implements Base {
     public void x(){
static <T> List<T> getList(Class<? extends T> type) {
     // T.x(); -> Error
return new ArrayList<T>();
public static void main(String[] args) {
List<Base> list2 = getList( Base.class );
</code>
Thanks,
Mohan

Answer 1

Do you mean that you can't write T.x()? That is completely normal: you couldn't write Derived.x() either. More importantly, here T is being erased to Object, so you couldn't do this either:
static <T> List<T> getList(Class<? extends T> type,T obj) {
    T.x()
}for that to work you would have to do this:
static <T extends Base> List<T> getList(Class<? extends T> type,T obj) {
    T.x()
}
