【Android API】java.util.List<E>

java.util.List<E>

属于公共接口，因此List<String> list = new List<String>();是无法实例化的。

已知间接子类：

AbstractList
<E>,
AbstractSequentialList <E>,
ArrayList <E>,
CopyOnWriteArrayList <E>,
LinkedList <E>,
Stack <E>,
Vector <E> 可以通过这些类来实例化。比如：

List<String> list = new ArrayList<String>();
