I'm taking a course on design patterns in software engineering and here I'm trying to understand the good and the bad way of design relating to "coupling" and "cohesion". I could understand the concept described in the following image. ![enter image description here][1] The example of code shown in the image is ambiguous to me, so I can't quite clearly get what exactly "Ask, don't tell!" approach mean. Could you please explain? [1]: https://i.sstatic.net/Tft7E.jpg
