This post helps you understand overview about Map API in the Java Collections Framework.
You know, a map stores elements in terms of key=value pair. Map<K, V> is the base interface for all kind of maps.
- Map Sub interfaces: ConcurrentMap<K, V>, SortedMap<K, V>, NavigableMap<K, V> and ConcurrentNavigableMap<K, V>.
- Map Abstract classes: AbstractMap<E>.
- Map Implementation classes:
- Hashtable<K, V>
- HashMap<K, V>
- LinkedHashMap<K, V>
- IdentityHashMap<K, V>
- ConcurrentHashMap<K, V>
- ConcurrentSkipListMap<K, V>
- EnumMap<K extends Enum<K>, V>
- WeakHashMap<K, V>
- TreeMap<K, V>
