大科、阿立和阿勇是大老板雄哥手下的三个马仔。在不明就里、稀里糊涂地受了雄哥的蒙骗后，三个一心梦想着能出人头地、大发横财的马仔招来了杀身之祸。就在东躲西藏、无处逃生之际，在阿立的提议下，三人前来投奔阿立的一个亲戚、南方武术学校的校长武舅舅。"If only my father and mother were here, they would be very surprised to see it!"Name: Lin Li　　因为她知道，她是星星的母亲。明玉仰着头笑着，她相信“艰苦，也要笑给天看”。A return value of false indicates that the ViewGroup has no child elements or that the child elements have not consumed the event.If I were to implement a pizza ordering system, I would definitely write the code like this, because this kind of code can be written subconsciously without consuming our brains. However, take a closer look at this code: the purpose of this method is to order pizza. However, the code for ordering pizza also needs knowledge about the production of pizza. This method must know all pizza. Worse still, if the types of pizza are to be expanded or pizza with poor sales volume are to be deleted in the future, then the code for ordering pizza will be modified. It looks very bad and should be revised. Our first step must be to separate the code for producing Pizza from the code for ordering pizza, because you should not let the code for ordering Pizza know the logic for producing pizza, but should hand over the logic for producing Pizza to a special type. In this way, we can cope with future changes-if we want to add or delete pizza, we can directly modify the producer of pizza without affecting the logic of ordering pizza.
