1：父类

package com.imooc.car;
/*
* 总共有三种车型：载人Passenger，载货Goods，载人载货Loader
* Car 为这三种车型的父类
* 有4种属性：
* 编号 = number
* 品牌 = brand
* 租金/天 = fee
* 载人容量 = personCapacity
* 载货容量 = goodCapacity
*/
public class Car {
int number;
String brand;
double fee;
int personCapacity;
double goodCapacity;

public Car(int number, String brand, double fee){ //构造方法
this.number = number;
this.brand = brand;
this.fee = fee;
}

public int getNumber(){
return number;
}

public String getBrand(){
return brand;
}

public double getFee(){
return fee;
}

public int getPersonCapacity(){
return personCapacity;
}

public double getGoodCapacity(){
return goodCapacity;
}

}

2：子类一：（载人的车）

package com.imooc.car;
/*
* PassengerCar为载人汽车，除了Car中的属性之外还有载人容量 personCapacity
*/
public class PassengerCar extends Car{

private int personCapacity;

public PassengerCar(int number, String brand, double fee, int personCapacity) {

super(number, brand, fee);
this.personCapacity = personCapacity;
}

public int getPersonCapacity() {
return personCapacity;
}

@Override
public String toString() {
return number + "\t" + brand + "\t" + fee + "元/天\t" + personCapacity + "人\n";
}

}

3：子类二（载货汽车）

package com.imooc.car;

/*
* Goods为载货汽车，除了Car中的属性之外还有载货容量 goodCapacity
*/
public class Goods extends Car{

private double goodCapacity;

public Goods(int number, String brand, double fee, double goodCapacity) {

super(number, brand, fee);
this.goodCapacity = goodCapacity;

}

public double getGoodCapacity(){
return goodCapacity;
}

public String toString() {
return number + "\t" + brand + "\t" + fee + "元/天\t" + goodCapacity + "吨" + "\n";
}

}

4：子类四（载人载物车）

package com.imooc.car;

/*
* Loader为载人载货汽车，除了Car中的属性之外还有载人容量 personCapacity,载货容量goodCapacity
*/
public class Loader extends Car{

private int personCapacity;
private double goodCapacity;

public Loader(int number, String brand, double fee, int personCapacity, double goodCapacity) {

super(number, brand, fee);
this.personCapacity = personCapacity;
this.goodCapacity = goodCapacity;

}

public int getPersonCapacity() {
return personCapacity;
}

public double getGoodCapacity(){
return goodCapacity;
}

@Override
public String toString() {
return number + "\t" + brand + "\t" + fee + "元/天\t" +
personCapacity + "人\t" + goodCapacity + "吨\n";
}
}

5：主方法

package com.imooc.car;
import java.util.Scanner;

public class RentCars {

public static void main(String[] args){

Scanner input = new Scanner(System.in);
Car[] cars = new Car[6];

System.out.println("欢迎使用答答租车系统：");
System.out.println("您是否要租车？1、是0、否（请输入1或0）");
int input1 = input.nextInt();
if (input1 == 1){
System.out.println("下面是所有车的信息：");

cars[0] = new PassengerCar(1, "奥迪A4", 500.0, 4);
cars[1] = new PassengerCar(2, "马自达6", 400.0, 4);
cars[2] = new Loader(3, "皮卡雪6", 450.0, 4, 2);
cars[3] = new PassengerCar(4, "金龙", 800.0, 20);
cars[4] = new Goods(5, "松花江", 400.0, 4);
cars[5] = new Goods(6, "依维柯", 1000.0, 20);

System.out.println("序号\t" + "汽车名称\t" + "租金\t\t" + "容量(载人/载货)");
for(int i = 0; i < cars.length; i++){
System.out.println("编号:"+ (i+1) +" 品牌:"+ cars[i].getBrand()
+" 租金:"+ cars[i].getFee() +"/天载客量:"+ cars[i].getPersonCapacity()+"人"
+" 载货量:"+ cars[i].getGoodCapacity()+"吨" );
}
}else{
System.out.println("谢谢使用，再见！");
}

System.out.print("请输入你要租几种车：");
int rentNum = input.nextInt();

//selected用来保存客户选中了什么车型，以及每种车型的辆数，与car数组是对应关系
int[] selected = new int[6];

for (int i = 1; i <= rentNum; i++){
System.out.println("请输入第" + i + "种车型的序号：" );
int nums = input.nextInt() - 1;
System.out.println(cars[nums].getBrand() +"总共需要多少辆：");
int num = input.nextInt();
selected[nums] = num;
}

System.out.println("请输入租车天数：");
int daysNum = input.nextInt();

System.out.println("您的账单：--------------------------");
double total = 0;
for (int i = 0; i < cars.length; i++){
if (selected[i] !=0 ){
System.out.println(selected[i] + "辆" + cars[i].getBrand() +
" 总共载客量:"+selected[i]*cars[i].getPersonCapacity()+"人"+
" 总共载货量:"+selected[i]*cars[i].getGoodCapacity()+"吨"+
" "+daysNum+"天单项费用:"+selected[i]*cars[i].getFee()*daysNum+"元");
total += selected[i]*cars[i].getFee()*daysNum;
}
}
System.out.println("租车总费用：" + total + "元" + "\n" + "欢迎下次光临！------------------------");
}
}
