public class HashSetCollection {

public static void main(String[] args) {
Set<String> hs=new TreeSet<String>();
hs.add("hi");
hs.add("i");
hs.add("am");
hs.add("Abhishek");
hs.add("Awasthi");
hs.add("Abhishek Awasthi");
hs.add("Abhishek");
hs.add("Awasthi");
System.out.println("Size: "+hs.size());
System.out.println("Distinct Words : "+hs);
