Java实现汽车租赁系统(附代码)

本文介绍的是利用java编写一个控制台版的[达达租车系统],下面话不多说了,来看看详细实现方法吧。

实现目标

java编写一个控制台版的[达达租车系统]

实现功能

1.展示所有可租车辆

2.选择车型、租车量

3.展示租车清单,包含:总金额、总载货量及其车型、总载人量及其车型

三大分析

数据模型分析

业务模型分析

显示和流程分析

实现效果

租车页面

租车账单

实现思路

首先定义一个Car类,它包含基本功能:车名、载客数、载货量、日租金。接着创建三个小类,分别是客车类、货车类和皮卡类(既能载客又能载货),它们都继承Car类。最后需要一个主类,用于开启整个系统,调用每个小类。
