我也来交作业~第二季6-1

运行结果：

源代码：

#Main.java

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

public class Main {

public static void main(String[] args) {
  Car[] cars = {new Car("奥迪A4",4,0,500), new Car("马自达6",4,0,400), new Car("皮卡雪6",4,2,450), new Car("金龙",20,0,800), new Car("松花江",0,4,400), new Car("依维柯",0,20,1000)};
  if(askChoice1() == 1) {
   showCars(cars);
   askChoice2(cars);
  }
}

//欢迎界面
@SuppressWarnings("resource")
public static int askChoice1() {
  System.out.println("***欢迎使用答答租车系统***");
  System.out.println("您是否需要租车？1.是 2.否");
  Scanner input = new Scanner(System.in);
  int choice1 = input.nextInt();
  return choice1;
}

//租车信息
public static void showCars(Car[] cars) {
  System.out.println("****************租车类型及其价目表****************");
  System.out.println("序号\t汽车名称\t租金\t\t容量");
  for(int i = 0; i < 6; i++) {
   System.out.print(" " + (i + 1));
   cars[i].showCarsInfo();
  }
}

//租车账单
@SuppressWarnings("resource")

  }

  double price = 0.0;
  for(int i = 0; i < Num; i++)
   price += cars[No[i] - 1].getPrice() * days;
  System.out.println("**************总金额：" + price + "元**************");
}
}

#Car.java

public class Car {
private String Name;
private int peopleNum;
private int goodsNum;
private double Price;

public String getName() {
  return Name;
}

}

public Car(String name, int pNum, int gNum, double price) {
  Name = name;
  peopleNum = pNum;
  goodsNum = gNum;
  Price = price;
}

public void showCarsInfo() {
  System.out.println("\t" + getName() + "\t" + getPrice() + "元/天\t可载" + getPeopleNum() + "人\t" + getGoodsNum() + "吨");
}
}

各位大神有更好的解法或建议欢迎提出~
