## Uses of Class
java.util.AbstractMap

Packages that use AbstractMap
java.util | Contains the collections framework, legacy collection classes, event model, date and time facilities, internationalization, and miscellaneous utility classes (a string tokenizer, a random-number generator, and a bit array).
java.util.concurrent | Utility classes commonly useful in concurrent programming.
javax.print.attribute.standard | Package javax.print.attribute.standard contains classes for specific printing attributes.

Uses of AbstractMap in java.util

Subclasses of AbstractMap in java.util
`class` | `EnumMap<K extends Enum<K>,V>` A specialized `Map` implementation for use with enum type keys.
`class` | `HashMap<K,V>` Hash table based implementation of the `Map` interface.
`class` | `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).
`class` | `LinkedHashMap<K,V>` Hash table and linked list implementation of the `Map` interface, with predictable iteration order.
`class` | `TreeMap<K,V>` A Red-Black tree based `NavigableMap` implementation.
`class` | `WeakHashMap<K,V>` A hashtable-based `Map` implementation with weak keys.

Uses of AbstractMap in java.util.concurrent

Subclasses of AbstractMap in java.util.concurrent
`class` | `ConcurrentHashMap<K,V>` A hash table supporting full concurrency of retrievals and adjustable expected concurrency for updates.
`class` | `ConcurrentSkipListMap<K,V>` A scalable concurrent `ConcurrentNavigableMap` implementation.

Uses of AbstractMap in javax.print.attribute.standard

Subclasses of AbstractMap in javax.print.attribute.standard
`class` | `PrinterStateReasons` Class PrinterStateReasons is a printing attribute class, a set of enumeration values, that provides additional information about the printer's current state, i.e., information that augments the value of the printer's `PrinterState` attribute.
