public
Map.Entry<K,V> pollLastEntry()
Removes
and returns a key-value mapping associated with the greatest key in
this map, or null if the map is empty.
import java.util.*; class TreeMapPollLastEntry{ public static void main(String args[]){ TreeMap<Integer, String> myMap; Map.Entry<Integer,String> lastEntry; myMap = new TreeMap<> (); /* Add Elements to myMap */ myMap.put(2, "w"); myMap.put(4, "wx"); myMap.put(6, "wxy"); myMap.put(8, "wxyz"); System.out.println("Elements in myMap are"); System.out.println(myMap); lastEntry = myMap.pollLastEntry(); System.out.println("Last Entry in myMap is"); System.out.println(lastEntry); System.out.println("Elements in myMap are"); System.out.println(myMap); } }
Output
Elements in myMap are {2=w, 4=wx, 6=wxy, 8=wxyz} Last Entry in myMap is 8=wxyz Elements in myMap are {2=w, 4=wx, 6=wxy}
