Get higherEntry(K key) in Java NavigableMap Example

This Java Example shows how to Get higherEntry in Java NavigableMap object. To get an higherEntry of NavigableMap We use Map.Entry higherEntry(K key) method. This method returns a key-value mapping associated with the least key strictly greater than the given key, or null if there is no such key.

 Example: HigherEntryNavigableMap.java

package devmanuals.com;

import java.util.*;

public class HigherEntryNavigableMap {
	public static void main(String[] args) {
		NavigableMap<Integer, String> Nmap = new TreeMap<Integer, String>();
		Nmap.put(2, "two");
		Nmap.put(1, "one");
		Nmap.put(3, "three");
		Nmap.put(6, "six");
		Nmap.put(5, "five");
		System.out
		     .println("The higher entry of 4 is : " + Nmap.higherEntry(4));
		System.out
		     .println("The higher entry of 5 is : " + Nmap.higherEntry(5));

	}
}
