Extracted directly from JDK7.0 API documentation. ##Interfaces
| Name | Description |
|---|---|
| Collection | The root interface in the collection hierarchy. |
| Comparator | A comparison function, which imposes a total ordering on some collection of objects. |
| Deque | A linear collection that supports element insertion and removal at both ends. |
| Enumeration | An object that implements the Enumeration interface generates a series of elements, one at a time. |
| EventListener | A tagging interface that all event listener interfaces must extend. |
| Formattable | The Formattable interface must be implemented by any class that needs to perform custom formatting using the 's' conversion specifier of Formatter. |
| Iterator | An iterator over a collection. |
| List | An ordered collection (also known as a sequence). |
| ListIterator | An iterator for lists that allows the programmer to traverse the list in either direction, modify the list during iteration, and obtain the iterator's current position in the list. |
| Map<K,V> | An object that maps keys to values. |
| Map.Entry<K,V> | A map entry (key-value pair). |
| NavigableMap<K,V> | A SortedMap extended with navigation methods returning the closest matches for given search targets. |
| NavigableSet | A SortedSet extended with navigation methods reporting closest matches for given search targets. |
| Observer | A class can implement the Observer interface when it wants to be informed of changes in observable objects. |
| Queue | A collection designed for holding elements prior to processing. |
| RandomAccess | Marker interface used by List implementations to indicate that they support fast (generally constant time) random access. |
| Set | A collection that contains no duplicate elements. |
| SortedMap<K,V> | A Map that further provides a total ordering on its keys. |
| SortedSet | A Set that further provides a total ordering on its elements. |

| BitSet | This class implements a vector of bits that grows as needed. |
| Calendar | The Calendar class is an abstract class that provides methods for converting between a specific instant in time and a set of calendar fields such as YEAR, MONTH, DAY_OF_MONTH, HOUR, and so on, and for manipulating the calendar fields, such as getting the date of the next week. |
| Collections | This class consists exclusively of static methods that operate on or return collections. |
| Currency | Represents a currency. |
| Date | The class Date represents a specific instant in time, with millisecond precision. |

| EnumMap<K extends Enum,V> | A specialized Map implementation for use with enum type keys. |
| EnumSet<E extends Enum> | A specialized Set implementation for use with enum types. |
| EventListenerProxy | An abstract wrapper class for an EventListener class which associates a set of additional parameters with the listener. |
| EventObject | The root class from which all event state objects shall be derived. |
| FormattableFlags | FomattableFlags are passed to the Formattable.formatTo() method and modify the output format for Formattables. |
| Formatter | An interpreter for printf-style format strings. |
| GregorianCalendar | GregorianCalendar is a concrete subclass of Calendar and provides the standard calendar system used by most of the world. |
| HashMap<K,V> | Hash table based implementation of the Map interface. |
| HashSet | This class implements the Set interface, backed by a hash table (actually a HashMap instance). |
| Hashtable<K,V> | This class implements a hashtable, which maps keys to values. |
| IdentityHashMap<K,V> | This class implements the Map interface with a hash table, using reference-equality in place of object-equality when comparing keys (and values). |
| LinkedHashMap<K,V> | Hash table and linked list implementation of the Map interface, with predictable iteration order. |
| LinkedHashSet | Hash table and linked list implementation of the Set interface, with predictable iteration order. |
| LinkedList | Linked list implementation of the List interface. |
| ListResourceBundle | ListResourceBundle is an abstract subclass of ResourceBundle that manages resources for a locale in a convenient and easy to use list. |
| Locale | A Locale object represents a specific geographical, political, or cultural region. |
| Observable | This class represents an observable object, or "data" in the model-view paradigm. |
| PriorityQueue | An unbounded priority queue based on a priority heap. |
| Properties | The Properties class represents a persistent set of properties. |
| PropertyPermission | This class is for property permissions. |
| PropertyResourceBundle | PropertyResourceBundle is a concrete subclass of ResourceBundle that manages resources for a locale using a set of static strings from a property file. |
| Random | An instance of this class is used to generate a stream of pseudorandom numbers. |
| ResourceBundle | Resource bundles contain locale-specific objects. |
| ResourceBundle.Control | ResourceBundle.Control defines a set of callback methods that are invoked by the ResourceBundle.getBundle factory methods during the bundle loading process. |
