In Java, List
is an interface. That is, it cannot be instantiated directly.
Instead you can use ArrayList
which is an implementation of that interface that uses an array as its backing store (hence the name).
Since ArrayList
is a kind of List
, you can easily upcast it:
List<T> mylist = new ArrayList<T>();
This is in contrast with .NET, where, since version 2.0, List<T>
is the default implementation of the IList<T>
interface.
