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"); System.out.println(map); } }
The code above generates the following result.
