Before learning the design pattern, readers must establish a kind of consciousness, that is, the design pattern is not only a method and technology, but also an idea and a methodology. It has nothing to do with the specific language. The main purpose of learning design patterns is to establish object-oriented ideas, program to the interface as much as possible, with low coupling and high cohesion, so that the programs you design can be reused as much as possible. "Specious. Learning design patterns can better understand object-oriented ideas. Design patterns are some design skills and tricks. Don't rise to ideas and methodologies, okay?"Syfy宣布《双螺旋》获得第二季13集续订的消息。
