java實現(xiàn)簡單租車系統(tǒng)

更新時間：2019年01月29日 10:17:46 作者：淺然_

這篇文章主要為大家詳細介紹了java實現(xiàn)簡單租車系統(tǒng)，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本文實例為大家分享了java實現(xiàn)租車系統(tǒng)Demo，供大家參考，具體內(nèi)容如下

這也是參考了mooc上的一個基礎項目，所以拿來寫一下。不過我的Demo肯定有不好或者錯誤的地方，歡迎指出

1、項目功能/需求

a、展示所有可租車輛
b、選擇車型、租車量
c、展示租車清單，包含：總金額、總載貨量、總載客量

2、項目系統(tǒng)UML圖

3、項目源碼Demo

Car類

package Car.rental;

public class Car {
 private String name;
 private int rent;
 private int passenger;
 private double volume;
 public String getName() {
 return name;
 }
 public void setName(String name) {
 this.name = name;
 }
 public int getRent() {
 return rent;
 }
 public void setRent(int rent) {
 this.rent = rent;
 }
 public int getPassenger() {
 return passenger;
 }
 public void setPassenger(int passenger) {
 this.passenger = passenger;
 }
 public double getVolume() {
 return volume;
 }
 public void setVolume(double volume) {
 this.volume = volume;
 }

}

 System.out.println("請問您是否要租車：1.是 2.否");
 Scanner scan=new Scanner(System.in);
 String input=scan.next();
 if(input.equals("1"))

  int all_rent = 0;//總租金
  int all_passenger=0;//總載客
  double all_volume=0.0;//總載貨
  System.out.println("您可租車的類型及其價目");
  System.out.println("序號\t汽車名稱\t租金\t容量\t");
  for(int i=0;i<Allcar.length;i++)
  {
  if(Allcar[i] instanceof Truck)
  {
   System.out.println((i+1)+"\t"+Allcar[i].getName()+"\t"+Allcar[i].getRent()+"\t"+"載貨："+Allcar[i].getVolume());

  }
  }
  System.out.println("請輸入您要租車的數(shù)量");
  int sum=scan.nextInt();
