classes (a string tokenizer, a random-number generator, and a bit array). | 
| java.util.concurrent | Utility classes commonly useful in concurrent programming. | 
| javax.management | Provides the core classes for the Java Management Extensions. | 
| javax.management.relation | Provides the definition of the Relation Service. | 
| javax.print.attribute.standard | Package javax.print.attribute.standard
contains classes for specific printing attributes. | 
| Modifier and Type | Class and Description | 
|---|---|
| class  | AbstractList<E>This class provides a skeletal implementation of the  Listinterface to minimize the effort required to implement this interface
 backed by a "random access" data store (such as an array). | 
| class  | AbstractQueue<E>This class provides skeletal implementations of some  Queueoperations. | 
| class  | AbstractSequentialList<E>This class provides a skeletal implementation of the List
 interface to minimize the effort required to implement this interface
 backed by a "sequential access" data store (such as a linked list). | 
| class  | AbstractSet<E>This class provides a skeletal implementation of the Set
 interface to minimize the effort required to implement this
 interface. | 
| class  | ArrayDeque<E>Resizable-array implementation of the  Dequeinterface. | 
| class  | ArrayList<E>Resizable-array implementation of the List interface. | 
| class  | EnumSet<E extends Enum<E>>A specialized  Setimplementation for use with enum types. | 
| class  | HashSet<E>This class implements the Set interface, backed by a hash table
 (actually a HashMap instance). | 
| class  | LinkedHashSet<E>Hash table and linked list implementation of the Set interface,
 with predictable iteration order. | 
| class  | LinkedList<E>Doubly-linked list implementation of the  ListandDequeinterfaces. | 
| class  | PriorityQueue<E>An unbounded priority queue based on a priority heap. | 
| class  | Stack<E>The  Stackclass represents a last-in-first-out
 (LIFO) stack of objects. | 
| class  | TreeSet<E>A  NavigableSetimplementation based on aTreeMap. | 
| class  | Vector<E>The  Vectorclass implements a growable array of
 objects. | 
| Modifier and Type | Class and Description | 
|---|---|
| class  | ArrayBlockingQueue<E>A bounded blocking queue backed by an
 array. | 
| class  | ConcurrentLinkedDeque<E>An unbounded concurrent deque based on linked nodes. | 
| class  | ConcurrentLinkedQueue<E>An unbounded thread-safe queue based on linked nodes. | 
| class  | ConcurrentSkipListSet<E>A scalable concurrent  NavigableSetimplementation based on
 aConcurrentSkipListMap. | 
| class  | CopyOnWriteArraySet<E>A  Setthat uses an internalCopyOnWriteArrayListfor all of its operations. | 
| class  | DelayQueue<E extends Delayed>An unbounded blocking queue of
  Delayedelements, in which an element can only be taken
 when its delay has expired. | 
| class  | LinkedBlockingDeque<E>An optionally-bounded blocking deque based on
 linked nodes. | 
| class  | LinkedBlockingQueue<E>An optionally-bounded blocking queue based on
 linked nodes. | 
| class  | LinkedTransferQueue<E>An unbounded  TransferQueuebased on linked nodes. | 
| class  | PriorityBlockingQueue<E>An unbounded blocking queue that uses
 the same ordering rules as class  PriorityQueueand supplies
 blocking retrieval operations. | 
| class  | SynchronousQueue<E>A blocking queue in which each insert
 operation must wait for a corresponding remove operation by another
 thread, and vice versa. | 
| Modifier and Type | Class and Description | 
|---|---|
| class  | AttributeListRepresents a list of values for attributes of an MBean. | 
| Modifier and Type | Class and Description | 
|---|---|
| class  | RoleListA RoleList represents a list of roles (Role objects). | 
| class  | RoleUnresolvedListA RoleUnresolvedList represents a list of RoleUnresolved objects,
 representing roles not retrieved from a relation due to a problem
 encountered when trying to access (read or write) the roles. | 
| Modifier and Type | Class and Description | 
|---|---|
| class  | JobStateReasonsClass JobStateReasons is a printing attribute class, a set of enumeration
 values, that provides additional information about the job's current state,
 i.e., information that augments the value of the job's  JobStateattribute. |
