What is SortedMap?
SortedMap is an interface in collection framework. This interface extends Map interface and provides a total ordering of its elements (elements can be traversed in sorted order of keys).

SortedMap is an interface in collection framework. This interface extends Map interface and provides a total ordering of its elements (elements can be traversed in sorted order of keys). Exampled class that implements this interface is TreeMap.Click to see full answer. Likewise, people ask, how does a TreeMap work?TreeMap in Java. The TreeMap is used to implement Map interface and NavigableMap along with the Abstract Class. Also, all its elements store in the TreeMap are sorted by key. TreeMap performs sorting in natural order on its key, it also allows you to use Comparator for custom sorting implementation.Furthermore, what is the difference between HashMap and TreeMap? HashMap is implemented as a hash table, and there is no ordering on keys or values. TreeMap is implemented based on red-black tree structure, and it is ordered by the key. LinkedHashMap preserves the insertion order. Hashtable is synchronized in contrast to HashMap . Correspondingly, does TreeMap sort on key or value? A TreeMap is always sorted by the keys, anything else is impossible. A Comparator merely allows you to control how the keys are sorted. If you want the sorted values, you have to extract them into a List and sort that.What is TreeMap in Java with examples?TreeMap in Java with Example. By Chaitanya Singh | Filed Under: Java Collections. TreeMap is Red-Black tree based NavigableMap implementation. It is sorted according to the natural ordering of its keys. TreeMap class implements Map interface similar to HashMap class.
