根據所學知識，編寫一個控制臺版的租車系統
功能：1、 展示所有可租車輛
2、 選擇車型、租車輛
3、 展示租車清單，包含：總金額、總載貨量及其車型、總載人量及其車型
代碼參考imooc中[JavaEE]課程Demo編寫
父類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 的子類——載人汽車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 的子類——載貨汽車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 的子類——載人載貨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;
}
}
主函數：
