Which dry fruit have dry and hard walls and which are with juicy and fleshy walls?

Dry fruits with dry and hard walls include types like nuts (e.g., acorns and hazelnuts) and capsules that typically do not open at maturity. In contrast, fruits with juicy and fleshy walls are known as fleshy fruits, such as berries (e.g., blueberries) and drupes (e.g., peaches), which contain a succulent pericarp that is often consumed.
