The above is only a model of "Long En" bicycle, If you need to generate other types of bicycles, Other subclasses can be written. The most important advantage of factory mode is that some of the same methods can be implemented. We can write code in the parent class for these same methods. If we need to implement specific business logic, we can rewrite the parent class's methods in the subclass to implement our own business logic. In terms of professional terms, there are two points: First, weaken the coupling between objects and prevent code duplication. Instantiating a class in a method eliminates repetitive code. Second: Repetitive code can be written in the parent class. Subclasses inherit all member attributes and methods of the parent class. Subclasses only focus on implementing their own business logic.Package Explosion Injury% 40%感觉活不下去的苍蝇，无法诉说梦想，过着OL生活…A billionaire with questionable priorities re-examines his life after discovering his grandfather's journal.1, the normal group of strange scourge, one scourge caused 3 scourge damage; Single Scourge, 1 Scourge Causes 2 Scourge Damage.Modern Pentathlon我欲斩三尸，得成混元道果，哪里知道，现只斩得两个，这自身却不曾斩得，未悟得那诸法皆空的道理。
