public class GetSubSetFromTreeSet {

	public static void main(String[] args) {
		
		//create TreeSet.
		TreeSet treeSet = new TreeSet();
		
		treeSet.add("A");
		treeSet.add("B");
		treeSet.add("C");
		treeSet.add("D");
		
		/*
		 * To get the sub Set from Java TreeSet use subSet method of TreeSet.
		 */
		SortedSet sortedSet = treeSet.subSet("B","D");
		
		System.out.println("SortedSet Contains : " + sortedSet);
