Is there any way to pass a method of a generic type as a parameter? What I try to achieve is something like this:
ListUtils.mapObjectToField( entries, Contact.getZipCode );
I pass a List<T>
and a method from the generic class T
. So far I am fine with the generic List but I am not able to achieve the method call.
public static <T, U> List<U> mapObjectToField( List<T>elements, /*generic method*/ )
{
List<U> result = new ArrayList<>();
for ( T current : elements )
{
result.add(current./*generic method*/);
}
return result;
}
No Java 8 as I am coding for Android min SDK 14.
