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.

一九二八年，东北军的屯垦部队营长彭兴华在兴安岭我方的军事禁区逮捕了以进行农业考察做晃子，擅自闯入军事禁区进行间谍活动并肆意枪杀我方边民、纵火焚烧民房的日本关东军军事间谍大野建二小组。依照有权处决敌方军事间谍的国际法规，出于对大野建二等间谍肆意杀人放火的憎恨，彭兴华下令处决了大野建二等人，但当时的东北地方政府，对日本关东军奉行极为软弱的政策，彭兴华为避追查，只得离开部队回乡，他打定主意去找张学良申诉，并主张对日强硬。龙山的大户程八爷，是一个爱国的士绅，早年他和彭兴华的父亲同闯关东，在东北军中服役。因为与日本关东军发生冲突，彭兴华的父亲为掩护程八爷而死，程八爷感念救命之恩，将彭兴华收为义子抚养成人。彭兴华长大后为报家仇国恨，毅然投军。松花江的支流桦树河子盛产砂金，并且还养育着清朝时期的稀世珍宝—东珠。桦树河子的宝藏吸引了日本拓荒团和关东军的垂涎，以关东军特务川口正雄为代表的日本侵略者千方百计想把桦树河子的开采权纳为日本开拓团所有，并把地照拿到手。而桦树河子地段分为上、中、下三段为程八爷、县商
"That what, The main reason I'm saying this is that I know a lot about dogs, At least the common types on the market, As long as the "name has a surname", There is nothing I can't call, but the kind of dog that rushed up in the battle at that time was simply too fierce.

Iterator patterns are created for collection objects, For collection objects, It must involve the addition and deletion of collection elements, and certainly supports the operation of traversing collection elements. If the traversal operation is also placed in the collection object at this time, the collection object will bear too many responsibilities. At this time, the responsibilities can be separated and the traversal of the collection can be placed in another object, which is the iterator object.
However, writing code in this way has the following disadvantages:
The essence of these 23 design patterns is the practical application of object-oriented design principles, and it is a full understanding of the encapsulation, inheritance and polymorphism of classes, as well as the association and combination of classes.
