Wouldn't Treet originalTreets = treets[0] just give you one element at index position 0?

Hello, I'm confused as to how originalTreets can accommodate the following code: for (String hashtag: originalTreet.getHashTags()) { System.out.println(hashtag);

originalTreets only stores one element that is in treets[0] index at 0?

Hey Kshatriiya ,

yes there is only one element stored at treets[0]. Also, in the video the variable is called "originalTreet", without the "s" that you wrote in your question.

Then on this one treet the getHashTags() method is called which returns a list of strings, which are the hashtags. The for-each loop then iterates over each one of them and prints it out.
