As far as a class is concerned, there should be only one reason for it to change. If a class assumes too many responsibilities, it is tantamount to coupling these responsibilities together. Changes in one responsibility may affect other responsibilities. In addition, coupling multiple responsibilities together will also affect reusability.民心所向，在任何时候都至关重要，从现在开始就潜移默化地影响自然最好不过。一批拥有特殊能力的小朋友，通过老教授的时空穿梭机来到了宋代的开封府。与包公、展昭等共同经历了破获地牢命案、客栈智擒偷银贼、巧查梁王府窃案、义取长生不老药、揭露真假父子、给包爷爷治病、向梁国老借粮、智劝庞太师、力查科举考等多个系列事件的全过程，经历过无数次的历险后，佳乐等小朋友终于发现了自身的缺点，也明白了俞教授的良苦用心，他们体验到成功的喜悦，发现人生的价值与目标，增强了集体荣誉感和责任心，以及与人为善、开朗活泼的性格，坚强的意志品质；同时也提高了热爱大自然、保护大自然的意识和对大自然审美情趣。改编自中国知名作家郑渊洁原著《舒克和贝塔历险记》，故事衔接上一季，再续经典。讲述舒克贝塔在皮皮鲁的帮助下建立机场，成立航空公司，维护着森林里小动物们的出行安全，也让更多老鼠通过劳动换取了食物，改变着老鼠的坏名声。然而这一切被海盗鼠们盯上，他们设计圈套，抢占机场......几经周旋、奋战，舒克贝塔和机场员工齐心协力战胜了海盗。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).
