Little help here.. Anyone ??

I want to clarify whether I am on right path here ..

Recalling some previous code, treet was a message from Craig Dennis seondTreet was a message from journeyToCode

Craig made an array of treets = [treet, secondTreet]

so, In the code below:

Treet originalTreet = treets[0];

here, we are getting the array of [a message from Craig Dennis] ..right ? and then we are storing it in originalTreet..right ?

Yes, exactly. Just to be clear, the message by Craig is a treet type object, the first item of the treets array. And the term "storing" in this context actually means that we are assigning another "pointer" to this object (with the name originalTreet), by which we can reference it instead of treet or treets[0].

No, but when I ran it, the "Treets.ser" file, (command --- cat Treets.ser), the messge which he has uploaded in the treets is different now(some other message with lot of hash tags). Then how come, only #treet pop-out as an output ?

Could you please share the full code, or at least the part which gives you the confusion (I'm a little lost, it was a while ago that I've been doing this course)? (See the Markdown Cheatsheet link below the text box for formatting it properly.)
