NavigableMap lastEntry() method in Java
The NavigableMap lastEntry() method returns a key-value mapping associated with the greatest key in this map.
Let us first create a NavigableMap and add some elements to it −
NavigableMap<Integer,String> n = new TreeMap<Integer,String>(); n.put(5, "Tom"); n.put(9, "John"); n.put(14, "Jamie"); n.put(1, "Tim"); n.put(4, "Jackie"); n.put(15, "Kurt"); n.put(19, "Tiger"); n.put(24, "Jacob");
Now, get the last entry −
n.lastEntry();
The following is another example to get last entry from NavigableMap −
Example
import java.util.*; public class Demo { public static void main(String[] args) { NavigableMap<String, Integer> n = new TreeMap<String, Integer>(); n.put("A", 498); n.put("B", 389); n.put("C", 868); n.put("D", 988); n.put("E", 686); n.put("F", 888); n.put("G", 999); n.put("H", 444); n.put("I", 555); n.put("J", 666); System.out.println("NavigableMap elements...
"+n); System.out.println("Last Entry is "+n.lastEntry()); } }
Output
NavigableMap elements... {A=498, B=389, C=868, D=988, E=686, F=888, G=999, H=444, I=555, J=666} Last Entry is J=666
