航空公司题目集总结Blog
前言
这两次题目涉及到了以下知识点：
- 面向对象编程(OOP)概念：类和对象，封装，继承，多态
- Java核心语法：控制结构，数据类型，字符串处理，输入输出
- 集合框架：ArrayList以及相关方法操作
- 抽象类：定义了抽象类GetFinalPrice、BillingPrinciples、ShowOrder和Payment，其中包含抽象方法，要求子类必须实现
- 继承与方法重写：子类（如Individual、Corporate、NormalGoods等）继承父类并重写父类的抽象方法（如getPrice()、getRate()）
通过@Override注解确保方法重写的正确性 - 设计模式应用：通过BillingPrinciples和GetFinalPrice的实现，不同的计费策略可以灵活替换
我觉得这两次题目算法上难度并不高，主要考察面向对象的设计能力。

航空快递以速度快、安全性高成为急件或贵重物品的首选。本题目要求对航空货运管理系统进行类设计，具体说明参看说明文件。
输入格式:
按如下顺序分别输入客户信息、货物信息、航班信息以及订单信息。
客户编号
客户姓名
客户电话
客户地址
运送货物数量
[货物编号
货物名称
货物宽度
货物长度
货物高度
货物重量
]//[]内的内容输入次数取决于“运送货物数量”，输入不包含“[]”
航班号
航班起飞机场
航班降落机场
航班日期（格式为YYYY-MM-DD）
航班最大载重量
订单编号
订单日期（格式为YYYY-MM-DD）
发件人地址
发件人姓名
发件人电话
收件人地址
收件人姓名
收件人电话
输出格式:
如果订单中货物重量超过航班剩余载重量，程序输出The flight with flight number:航班号 has exceeded its load capacity and cannot carry the order. ，程序终止运行。
如果航班载重量可以承接该订单，输出如下：
客户：姓名(电话)订单信息如下：
-----------------------------------------
航班号：
订单号：
订单日期：
发件人姓名：
发件人电话：
发件人地址：
收件人姓名：
收件人电话：
收件人地址：
订单总重量(kg)：
微信支付金额：
货物明细如下：

解释：
在第一次迭代的基础上，我改善了类的写法，移除了内部类，也根据题目要求增加了用户、支付方式、货物类，同时也满足可扩展性。具体可参考以下类图

心得：
在上一次题目的基础上，因为上一次我就遵循了单一职责原则、里氏代换原则、开闭原则、合成复用原则，所以我改起来速度可以比较快，但是最后一直卡在一个点过不去，结果发现是“Wechat”的c不小心大写了，浪费了很多时间，这也再次警示我一定要好好审题。
踩坑心得
第一次迭代
- [1]
刚开始一直非零返回，后面发现是在创建货物list循环时没有每一次都重新创建一个货物实例，导致非零返回
第二次迭代
-
[1]
错误审题将“Wechat”的c大写了，导致答案错误 -
[2 ]
由于没有创建参数来简化代码，所以我很多地方要调用很多次方法，例如order.getPrice().getPrice(order.totalPrice())，导致错了很多次，逻辑容易混乱

- [1] 缺乏注释
带注释的行的百分比为 0.0%，这会给后续的代码维护和理解带来极大困难，尤其是对于新接手项目的开发者，很难快速理解代码的功能和设计意图。
- [2] 方法复杂度偏高
在 “航空 2.txt” 中，Main.main() 的复杂度为 11，语句数达 100，存在大量输入逻辑和对象初始化，导致方法臃肿。
- [3] 耦合度高
DisplayOrder.showOrder()直接调用 order 对象的多层方法（如 order.getCustomer().getName()），未缓存中间结果
我需要增加注释，拆分 Main.main() 方法，将输入逻辑、对象创建、业务处理拆分为独立方法或类（如 InputService、OrderFactory），优化类间，降低耦合度。

- [1] 缺乏注释
带注释的行的百分比为 0.0%，这会给后续的代码维护和理解带来极大困难，尤其是对于新接手项目的开发者，很难快速理解代码的功能和设计意图。
- [2] 复杂度与语句数超标
主方法（Main.main ()）严重臃肿，方法承担输入处理、对象创建、业务逻辑、输出展示等全部职责，违反单一职责原则。包含大量嵌套的 if-else 条件判断（如客户类型、货物类型、支付方式的分支），逻辑混乱。连续读取 20 + 行输入，未拆分任何子方法，导致代码可读性极差。
- [3] 抽象类与接口滥用
类数量增至 18 个（航空 1 为 12 个），但部分抽象类（如 GetFinalPrice、Payment）仅包含单一方法，适合用接口替代。
- [4] 耦合度强
Goods 类的 getPrice() 方法直接调用 billingPrinciples.getRate()，未隔离策略细节，导致 Goods 与计费规则强耦合。
我要多写注释，同时尽量优化复杂的方法，简化思路和写法，做到职责单一性，减少方法调用，降低耦合度。重构 Main.main ()，将输入处理（如 readCustomer()）、对象创建（如 createOrder()）、业务逻辑（如 calculatePrice()）拆分为独立方法或服务类，避免主方法直接操作细节。
总结
在完成这两次的题目集的过程中，我深刻理解了抽象类的使用，熟练了继承与多态的用法，也深入锻炼了自己的面向对象的思维。并且在这次题目中我深刻认识到了审题的重要性，花足够多的时间仔细理解读题，设计好结构比争分夺秒开始动手重要多了。而且我也在自己代码不足的地方有了一定的认识，以后肯定会在这方面多花精力。但是在遵循原则上我并没有完全遵循，还是有一些不足，会在下一次的题目集里慢慢成长改变。这次的题目也很需要耐心，有很多细节是要用心才能发现问题，这也培养了我坚持不懈和耐心仔细的品质。
