OOP第三次总结分析作业

一、前言

本次为对题目集7-9的分析总结，题量越来越少，反之，题目难度有明显的提升。

题目集7的知识点：

继承、多态的应用；
ArrayList泛型的应用方法
Comparable接口及泛型的应用
单一职责原则的应用
“开-闭”原则的应用

题目集8的知识点：

对象的封闭性，可拓展性
各实体类之间的关系，一对多的组合关系
单一职责原则的应用

题目集9的知识点：

继承、多态及抽象类的应用

二、设计与分析

1.题目集7两题的递进式设计分析总结：

①shape类实现Comparable<>接口，由circle类、rectangle类、triangle类和trapezoid类继承shape类，三个类中都有获得各个图形面积的方法；

设计DealCardList类获取主类中的输入，再对数据进行分类，排序、判断以及输出。

import java.util.Collections;
import java.util.List;
import java.util.Scanner;
import java.util.TreeSet;
public class Main {
    //在Main类中定义一个静态Scanner对象，这样在其它类中如果想要使用该对象进行输入，则直接
//使用Main.input.next…即可（避免采坑）

    public static void main(String[] args){
        
        ArrayList<Integer> list = new ArrayList<Integer>();

②7-2在7-1的基础上进行稍加改动，只需添加各自的arraylist链表存入图形数据，输出添加一些数据即可

2.题目集8和9ATM仿真题目的设计分析总结：

①创建银行类、账户类、ATM类、银行卡类分别管理输入的信息，储存于链表内，类与类之间实现调用关系实现相关输出，采用迭代器判断数据是否合理。

相关类图如下：

②在题目集8的基础上添加贷款的功能，只需添加判断即可
