第二次blog作业-航空货运管理系统总结
航空货运管理系统
前言
这两次作业是对继承等知识的考察，但总来说不是非常难，但最大的不同是这两次作业，没有给我们类图作为参考，需要自己设计类来进行作业，在起初，我只是按照输出的不同部分进行分组，其实这是非常不熟练的表现，在五一前后我也对array list不是十分的熟练导致第一次作业完成需要借助ai的帮忙，这也导致我最后完成的十分糊涂，其实我自己也十分清楚我没有对这次作业的核心搞明白，下面我们来详细的分析两次作业
设计与分析
第一次航空货运管理
第一次得知这次的题是没有类图的，我觉得这次的题可能也和上次的电梯一样十分困难，但是我仔细分析了一下题目发现，不是十分的困难，只需要将它给予的输入部分分类就可以十分有条理的设计出框架。
按照上面不同类型我将代码的类分为了
customer，goods，flight，和order类，起初并没有使用继承这个方法，只是建四个独立的类，但是后来自己完成并不会使用Array List这一知识点，下面是我的代码：
第一次代码
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int customerId = sc.nextInt();

Customer customer = new Customer(customerId, customerName, customerPhone, customerAddress);
int goodsCount = sc.nextInt();
sc.nextLine();
Goods[] goodsArray = new Goods[goodsCount];
for (int i = 0; i < goodsCount; i++) {
int goodsId = sc.nextInt();
sc.nextLine();
String goodsName = sc.nextLine();
int goodsWidth = sc.nextInt();
int goodsLength = sc.nextInt();
int goodsHeight = sc.nextInt();
double goodsWeight = sc.nextDouble();
sc.nextLine();
goodsArray[i] = new Goods(goodsName, goodsWidth, goodsLength, goodsHeight, goodsWeight);

可见编写的十分生疏，并没有使用复杂的知识点，并且在最后输出的地方也是用的简单的println，甚至有些类中的方法并没有使用

分析结果表示：类和接口数量：有 5 个。平均每个类的方法数：11.2 个 。平均每个方法的语句数：2.59 条。最复杂方法：是 Main.calculateChargeableRate() ，其行数为 93 行，复杂度达 7 ，复杂度较高，可能维护起来较困难。最大代码块深度：为 3 ，平均代码块深度 1.72 。在可读性和可维护性上存在明显不足，这其实是我代码存在的问题。
第二次航空货运管理系统
这一次我吸取的上次的教训，但是这次一次的题目我觉得相较于上次一片空白来说我熟练了好多，因为大体框架我并没有修改，只是我运用自己的见解，在部分类中添加了有关其“type”的变量，我在这其中犯得最傻的问题可能就是我在验证两个字符串是否相同时用的是“==”这种方式，不知道是我学术不精，还是我对于c语言的习惯，始终在这里报错，我交给ai后我才修改了这个问题，下面是我的代码：

其实我在第二次的作业中并没有加入其他的类，我只是在原有的基础上添加变量改动的很小，但其实我知道我这样导致我的代码，可改动的空间就很小，这样维护性也会很差，我并没有使用继承和抽象类的方法，下面是我这次代码的分析结果：
