What if for (Treet treet: treets) { for(String hashtags: treet) { doesn't contain a single String with hashtag?

Does it look back to the first for loop? Because if it doesn't, I feel like it would break the rest of the code.

Can someone confirm this for me please?

Thanks

If for-each is done on an empty array, the loop never executes because there is nothing to iterate over and it continues on with what it was doing.
