TreeMap.subMap(K fromKey, boolean fromInclusive, K toKey, boolean toInclusive) has the following syntax.
public NavigableMap <K , V> subMap(K fromKey, boolean fromInclusive, K toKey, boolean toInclusive)
In the following code shows how to use TreeMap.subMap(K fromKey, boolean fromInclusive, K toKey, boolean toInclusive) method.
/*w w w .j a v a 2 s . c o m*/ import java.util.NavigableMap; import java.util.TreeMap; 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 java2s.com"); System.out.println("Getting a portion of the map"); NavigableMap<Integer, String> treemapincl=treemap.subMap(1, true, 3, true); System.out.println("Sub map values: "+treemapincl); } }
The code above generates the following result.
