Factory Pattern: Factory Pattern is a frequently used pattern. Classes implemented according to Factory Pattern can generate instances of one of a group of classes according to the provided data. Usually, this group of classes has a common abstract parent class and implements the same methods, but these methods perform different operations for different data. First of all, we need to define a base class. Subclasses of this class implement methods in the base class through different methods. Then you need to define a factory class that can generate different subclass instances according to conditions. After getting an instance of a subclass, developers can call methods in the base class regardless of which subclass instance is returned.

He threw the cartridge sideways, He threw such a heavy thing so far away, It's almost farther than I threw a grenade, Because I don't know how many times the front of the position has been ploughed by artillery, Full of floating soil, It's very soft, So when the explosive cylinder landed, it was finally inserted obliquely on the ground. It was also impartially inserted in the most densely populated position of the group of strange dogs, Then the explosive barrel exploded, which was quite powerful. I felt that it was more powerful than a shell. The width of the whole position was completely covered by 10 meters in front of it.
