Hi friend,

import java.util.*;
import java.io.*;

public class SetHashset{

public static void main(String args[]){
Set<String> set = new HashSet<String>();
Set<String> dups = new HashSet<String>();
for (String a : args)
if(!set.add(a))
dups.add(a);
// Destructive set-difference
set.removeAll(dups);
System.out.println("Unique words: " + set);
System.out.println("Duplicate words: " + dups);
}
}
