B) Design principles. Many people have listed seven principles, such as single duty principle, opening and closing principle, Richter substitution principle, dependence inversion principle, interface isolation principle, composite reuse principle and Dimit principle. LSP, I elevated it to one of the three cornerstones of the object-oriented paradigm; Single responsibility and interface isolation are mainly used as the principle of responsibility division in object-oriented analysis/OOA, which you can not pay much attention to at this time. Relying on the inversion principle, I throw it away as garbage, because the opening and closing principle or directly "relying on abstract type principle" already contains the essence of relying on the inversion principle, while the dross of relying on the inversion principle is inherited by IoC. Of course, the pullback, I emphasize very much. Therefore, you need to master the abstract dependency principle (OCP), one-way dependency principle (including the learning of callbacks) and the minimum dependency principle (composite reuse principle, Dimit rule).

Each object has its corresponding state, and each state corresponds to some corresponding behaviors. If an object has multiple states, there will be many behaviors. Then the judgment of these states and the behavior completed according to the states will lead to multiple conditional statements, and if a new state is added, the existing code needs to be changed. This kind of design obviously violates the principle of opening and closing, and the state mode is used to solve such problems.
我记得这里的素斋味道好的很。
Polylactic acid (PLA) is a new bio-based and renewable biodegradable material, which is made of starch raw materials proposed by renewable plant resources (such as corn). Starch raw materials are saccharified to obtain glucose, then glucose and certain strains are fermented to produce high purity lactic acid, and polylactic acid with certain molecular weight is synthesized by chemical synthesis method. It has good biodegradability, can be completely degraded by microorganisms in nature under specific conditions after use, and finally generates carbon dioxide and water without polluting the environment, which is very beneficial to environmental protection and is recognized as an environment-friendly material. This thing is actually a long piece, and then "curled up" in it and wrapped in a cylinder shape. What's the use? You will see it in a short time.
Attackers can use ICMP/IGMP flood attacks and UDP flood attacks to directly launch distributed denial of service attacks that consume network broadband resources. However, this attack method is not only low, but also easy to find the source of the attack. Although attackers can hide by forging the source IP address, a better way is to use reflection attack technology.
