can List<Character> be instantiated?

when I write this, it has the error "cannot instantiate the type List < Character>"

Character[] ray = {'a','s','e'};
List<Character> l = new List<Character>(Arrays.asList(ray));

But when I write this, there is no error

Character[] ray = {'a','s','e'};
List<Character> l = Arrays.asList(ray);

So why is that?

edit: and what is the type of l in the second example?

The problem is that List is an interface (it defines some methods, but doesn't implement them). Try using a class that implements it, like ArrayList or LinkedList:

List<Character> l = new ArrayList<Character>(Arrays.asList(ray));
