import java.util.Iterator;
import java.util.NavigableMap;
import java.util.NavigableSet;
import java.util.TreeMap;
public class Main {
public static void main(String[] args) {
NavigableMap<String, Integer> navigableMap = new TreeMap<String, Integer>();
String[] letters = { "a", "b", "c" };
int[] ints = { 3, 2, 1 };
for (int i = 0; i < letters.length; i++){
navigableMap.put(letters[i], ints[i]);
}
System.out.println("Map = " + navigableMap);
System.out.println("Entry > c is " + navigableMap.higherEntry("c"));
}
