根据所学知识，编写一个控制台版的租车系统
功能：1、 展示所有可租车辆
2、 选择车型、租车辆
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
代码参考imooc中[JavaEE]课程Demo编写
父类Car：
package com.RentCar;
public class Car {
String name;
int money;
int people;
int goods;
public String getName() {
return name;
}
public int getMoney() {
return money;
}
public int getPeople() {
return people;
}
public int getGoods() {
return goods;
}
}
Car 的子类——载人汽车CarPeople：
package com.RentCar;
public class CarPeople extends Car{
String name;
int money;
int people;
public CarPeople(String name,int money,int people){
this.name = name;
this.money = money;
this.people = people;
}
@Override
public String toString() {
return this.name + "" + this.money + this.people;
}
public String getName() {
return name;
}
public int getMoney() {
return money;
}
public int getPeople() {
return people;
}
}
Car 的子类——载货汽车CarGoods：
package com.RentCar;
public class CarGoods extends Car {
String name;
int money;
int goods;
public CarGoods(String name,int money,int goods){
this.name = name;
this.money = money;
this.goods = goods;
}
@Override
public String toString() {
return this.name + this.money + this.goods;
}
public String getName() {
return name;
}
public int getMoney() {
return money;
}
public int getGoods() {
return goods;
}
}
Car 的子类——载人载货CarAll：
package com.RentCar;
public class CarAll extends Car {
String name;
int money;
int people;
int goods;
public CarAll(String name,int money,int people,int goods){
this.name = name;
this.money = money;
this.people = people;
this.goods = goods;
}
@Override
public String toString() {
return this.name + this.money + this.people + this.goods;
}
public String getName() {
return name;
}
public int getMoney() {
return money;
}
public int getPeople() {
return people;
}
public int getGoods() {
return goods;
