java实现简单租车系统
这篇文章主要为大家详细介绍了java实现简单租车系统，具有一定的参考价值，感兴趣的小伙伴们可以参考一下本文实例为大家分享了java实现租车系统demo，供大家参考，具体内容如下
这也是参考了mooc上的一个基础项目，所以拿来写一下。不过我的demo肯定有不好或者错误的地方，欢迎指出
1、项目功能/需求
a、展示所有可租车辆
b、选择车型、租车量
c、展示租车清单，包含：总金额、总载货量、总载客量
2、项目系统uml图
3、项目源码demo

system.out.println("请问您是否要租车：1.是 2.否");
scanner scan=new scanner(system.in);
string input=scan.next();
if(input.equals("1"))

int all_passenger=0;//总载客
double all_volume=0.0;//总载货
system.out.println("您可租车的类型及其价目");
system.out.println("序号\t汽车名称\t租金\t容量\t");
for(int i=0;i<allcar.length;i++)
{
