That is determined by the toString() method. Take a look at his implementation of this method on previous videos. You can override this method with your own code and decide how the object will be printed as a string.

Every time you create an object the REPL will call toString() method to show you information about the newly created object. You can define this method however you like. He decided not to print the Date.

Here is his code. You can change it and make the REPL print the Date.

public String toString(){
return "Treet: \"" + mDescription + "\" - @" + mAuthor;
}

Good Luck!
