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.咸阳围城依旧在继续。又名《孽爱囚情》，父辈的仇恨转移到男女主身上，女主不得已作为情妇住进男主家，复仇之路就此开始。媳妇，出事了。本来想着就此动手的时候，项羽的一份信函又送到了，项羽告诉英布让他密切注意义帝的动向。"Well, This is basically the case, After they all flew, they stayed in the air for a while.
