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).
Although the above code can meet the requirements, it is not easy to expand and difficult to read. If I want one or two conditions in the future, if I want to recharge 300 yuan successfully, I can win the 150 yuan red envelope, then I have to change the code inside at this time, so the coupling between business logic and code is relatively high, and I accidentally correct the wrong code. At this time, we try to use the responsibility chain mode to transfer objects in turn to realize it.

The incoming 23.65 m2 expanded to 25.05 m2 to the production office, and the space could meet the packaging operation. Die-cutting area: Change to Production Office, Due to the demand of diffusion capacity in the current die-cutting area, There is not enough space, The position needs to be readjusted, Auxiliary silo: The raw and auxiliary material silo is completely transformed into a fire-fighting passage, Set aside an area for transformation in SMT, as shown in Figure 8. Automatic first line: half assembly cable and south extension machine area, inner packaging area is transformed, assembly cable can be changed to automatic second line operation arrangement mode, i.e. Moving and adjusting cable spacing, inner packaging area adjusted to 6 6SMT part area is changed to auxiliary material bin (Figure, area can be used for production; 3.1 The die-cutting area is being expanded, and the number of die-cutting equipment to be applied for in the required area shall be determined, and the position adjustment shall be evaluated again. 3.2 Tuonan Film Sticking Machine suggests that the application should be transferred to ATV Headquarters by Manager Li of ATV Equipment Department. 3.3 The position of SMT's door will be readjusted as shown in the figure. There will be one automatic line and six manual lines, which will be one less manual line than the original arrangement. The length, width and height of fire engines are a decisive factor affecting the traffic capacity of fire lanes. Generally, the length of fire engines is greater than or close to 10m, the height is nearly 4m, and the width is nearly 2.5 m. Article 6.0. 2 of the "Construction Regulations" stipulates that the clear height and width of fire lanes passing through buildings shall not be less than 4m, which is determined according to the external dimensions of various fire vehicles used in China. Considering that the speed of fire engines is generally faster, a certain safety factor should be ensured on the width when passing through buildings to facilitate the fast speed of vehicles.
