Removing duplicates from a string in Java using collection HashSet

package collections;

import java.util.HashSet;
import java.util.Set;

public class DupsAndUniques {

public static void main(String[] args) {
Set<String> dups=new HashSet<String>();
Set<String> uniqs=new HashSet<String>();
for (String s:args)
{
if(!uniqs.add(s))
{
dups.add(s);
}
}
//To get the unique elements in unique variable
uniqs.removeAll(dups);

System.out.println("Duplicate Words: "+dups);
System.out.println("Unique Words: "+uniqs);

}

}
