Java Collection Tutorial - Java SortedMap.subMap(K fromKey, K toKey)


SortedMap.subMap(K fromKey, K toKey) has the following syntax.

SortedMap < K , V > subMap(K fromKey,   K toKey)


In the following code shows how to use SortedMap.subMap(K fromKey, K toKey) method.

import java.util.SortedMap;
import java.util.TreeMap;
/*  www . j  av  a 2 s . co m*/
public class Main {
  public static void main(String[] args) {
    SortedMap<String, Integer> sortedMap = new TreeMap<String, Integer>();
    sortedMap.put("A", 1);
    sortedMap.put("B", 2);
    sortedMap.put("C", 3);
    sortedMap.put("D", 4);
    sortedMap.put("E", 5);
    sortedMap.put("java2s", 6);
    SortedMap<String, Integer> map = sortedMap.subMap("B","E");


The code above generates the following result.
