Get SubMap in Java TreeMap Example

This Java Example shows how to Get sub map of Java TreeMap object. To get sub map of TreeMap We use SortedMap subMap(K fromKey, K toKey)  method. This method returns sub map from TreeMap object containing the entries between the specifies key values. 

 Example: SubMapFromTreeMap.java

package devmanuals.com;

import java.util.*;

public class SubMapFromTreeMap {
	public static void main(String args[]) {
		TreeMap Tmap = new TreeMap();
		Tmap.put(1, "Singh");
		Tmap.put(3, "Kumar");
		Tmap.put(4, "Kumar");
		Tmap.put(2, "Nagar");
		Tmap.put(6, "Prakash");
		SortedMap submap = Tmap.subMap(2, 5);
		System.out.println("The Sub Map from TreeMap is as : " + submap);

	}
}
