In order to prepare a zero-based environment, we will empty the rules provided by default in centos6 so that we can carry out experiments and use the iptables-F INPUT command to empty the rules in the INPUT chain of the filter table.

ShineThe 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.12个陌生人在空地上醒来。他们不知道自己在哪里，或者是如何到达这里的。他们不知道他们已经被选中，为了一个非常特殊的目的——捕猎。4.
