Cannot figure out why I am getting "Cannot find suitable printf method" error

I am getting the error on the last two print statements.

for( Treet treet : treets ) {
 allHashTags.addAll(treet.getHashTags());
 allMentions.addAll(treet.getMentions());
}
System.out.println("HashTags: %s %n", allHashTags);
System.out.println("Mentions: %s %n", allMentions);
 }

For formatted strings (strings using %s, and other placeholders like that) you have to use System.out.printf not System.out.println. That is what is causing an error in your code.
