   public static void main(String[] args) {
      
      TreeMap<Integer, String>  treemap = new TreeMap<Integer, String> ();
      
      // populating tree map
      treemap.put(2, "two");
      treemap.put(1, "one");
      treemap.put(3, "three");
      treemap.put(6, "six");
      treemap.put(5, "from java2s.com");
      
      // getting lower entry  
      System.out.println("Checking lower entry");
      System.out.println("Value is: "+ treemap.lowerEntry(5));
   }    
}
