Java Collection Tutorial - Java TreeMap.tailMap(K fromKey)


TreeMap.tailMap(K fromKey) has the following syntax.

public SortedMap<K, V> tailMap(K fromKey)


In the following code shows how to use TreeMap.tailMap(K fromKey) method.

import java.util.SortedMap;
import java.util.TreeMap;
/*from  w w w  . j  a  v  a2 s .c o m*/
public class Main {
   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");      
      System.out.println("Getting tail map");
      SortedMap<Integer, String>  treemapincl=treemap.tailMap(3);
      System.out.println("Tail map values: "+treemapincl);      

The code above generates the following result.
