This is the implementation of java.util.Arrays.asList: ()
public static <T> List<T> asList(T... a) { return new ArrayList<T>(a); }
How can that compile? I can’t find a constructor for ArrayList, AbstractList or AbstractCollection that accepts a parameter like T… och T[].

Okay, I think I see the confusion now.
The
ArrayListtype in question is a nested type within theArraysclass – it’s notjava.util.ArrayList.
