Whenever you print out an object it automatically goes to the objects class toString method and prints out whatever is in it.

toString () method returns a String that "textually represents" the object. When you print an object to Print Stream ( in this case System.out.printf("This is a new treet: %s : %n", treet) , the Print Stream calls toString () method inside the Treet Class to convert Treet to a string (textual representation)
