Example: TreeMap headMap(K toKey boolean inclusive) method in java

import java.util.NavigableMap;
import java.util.TreeMap;
public class TreeMapHeadMapBooleanInclusiveMethod
{
   public static void main(String[] args)
   {
      TreeMap<Integer, String> tm = new TreeMap<Integer, String>();
      NavigableMap<Integer, String> nm = new TreeMap<Integer, String>();
      tm.put(96, "violet");
      tm.put(93, "green");
      tm.put(20, "yellow");
      tm.put(36, "red");
      tm.put(53, "blue");
      // get head map inclusive 93
      nm = tm.headMap(93, true);
      System.out.println("Check values of TreeMap");
      System.out.println("Value is: " + nm);
   }
