Treet originalTreet = treets[0]; ??

I didn't get this part of code: 

    public static void main(String[] args) {
    Treet[] treets = Treets.load();
    System.out.printf("There are %d treets. %n",
                     treets.length);
    Treet originalTreet = treets[0];  //<<<<< ??????
    System.out.println("Hastags: ");
    for (String hashtag : originalTreet.getHashTags()) {
      System.out.println(hashtag);  
    }}

What we want to do is to check all the hashtags of the treets we are loading. But with that line of code, aren't we just checking the treet of index 0 in the treets array?

Hi Andrea!

Yeah we are just getting the "original tweet" I sent out there just to test out the logic of our method. We will loop all the treets in a bit.

Thanks!
