class |
AbstractCollection<E>
This class provides a skeletal implementation of the
Collection interface, to minimize
the effort required to implement this interface. |
class |
AbstractList<E>
This class provides a skeletal implementation of the
List interface to minimize the
effort required to implement this interface backed by a "random access" data store (such as an
array). |
class |
AbstractSet<E>
This class provides a skeletal implementation of the
Set interface to minimize the
effort required to implement this interface. |
class |
ArrayList<E>
Resizable-array implementation of the
List interface. |
class |
Stack<E>
The
Stack class represents a last-in-first-out (LIFO) stack of objects. |
class |
Vector<E>
The
Vector class implements a growable array of objects. |
