小苏(º﹃º ) 人气:0

一、使用技术

javaSE

二、实现功能

汽车租赁系统

具体要求如下:

使用面向对象的知识实现一个汽车租赁系统

1.汽车租赁信息表如下

2.类和属性

三、运行效果图


1.先创建一个汽车类作为父类,这里有汽车的公共属性:

public class Automobile {//汽车类
  private String licensePlate;//车牌
  private String brand;//品牌
  private int rent;//租金

  public Automobile() {
  }

  public Automobile(String licensePlate, String brand, int rent) {
    this.licensePlate = licensePlate;
    this.brand = brand;
    this.rent = rent;
  }

  public String getLicensePlate() {
    return licensePlate;
  }

  public void setLicensePlate(String licensePlate) {
    this.licensePlate = licensePlate;
  }

  public String getBrand() {
    return brand;
  }

  public void setBrand(String brand) {
    this.brand = brand;
  }

  public int getRent() {
    return rent;
  }

  public void setRent(int rent) {
    this.rent = rent;
  }
}

2.创建一个轿车类,继承汽车类的属性

public class Car extends Automobile{//轿车
  private String model;//型号

  public Car(String model) {
    this.model = model;
  }

  public Car(String licensePlate, String brand, int rent, String model) {
    super(licensePlate, brand, rent);
    this.model = model;
  }

  public String getModel() {
    return model;
  }

  public void setModel(String model) {
    this.model = model;
  }
}

3.创建一个客车类,继承汽车类的属性

public class Passengercar extends Automobile{//客车
private String seatingCapacity;//座位数

  public Passengercar(String seatingCapacity) {
    this.seatingCapacity = seatingCapacity;
  }

  public Passengercar(String licensePlate, String brand, int rent, String seatingCapacity) {
    super(licensePlate, brand, rent);
    this.seatingCapacity = seatingCapacity;
  }

  public String getSeatingCapacity() {
    return seatingCapacity;
  }

  public void setSeatingCapacity(String seatingCapacity) {
    this.seatingCapacity = seatingCapacity;
  }
}

4.创建测试类,用于实现这个系统

import java.util.Scanner;

public class TestAutomobile {
  public static void main(String[] args) {


    Car c1 = new Car("京NY28588", "宝马X6", 800, "1");
    Car c2 = new Car("京CNY3284", "宝马550i", 600, "1");
    Car c3 = new Car("京NT37465", "别克林荫大道", 300, "1");
    Car c4 = new Car("京NT969968", "别克GL8", 600, "1");

    Passengercar p1 = new Passengercar("京6566754", "金杯,16座", 800, "2");
    Passengercar p2 = new Passengercar("京8696997", "金龙,16座", 800, "2");
    Passengercar p3 = new Passengercar("京9696996", "金杯,34座", 1500, "2");
    Passengercar p4 = new Passengercar("京8696998", "金龙,34座", 1500, "2");
    Scanner sc = new Scanner(System.in);

    System.out.println("***********************欢迎光临秋名山守望者汽车租赁公司***********************");
    while (true){
      System.out.println("1、轿车  2、客车");
      System.out.println("请选择你要租赁的汽车类型:");
      String a=sc.next();
      if (a.equals("1")){//轿车
        System.out.println("请选择你要租赁的汽车品牌:1、别克 2、宝马");
        String a1=sc.next();
        if (a1.equals("2")){//宝马
          System.out.println("请选择你要租赁的汽车类型:1、X6 2、550i");
          String a2=sc.next();
          if (a2.equals("2")){//550i
            System.out.println("请选择你要租赁的天数");
            double a3=sc.nextInt();
            System.out.println("分配给您的汽车牌号是:"+c2.getLicensePlate());
            System.out.print("您需要支付的租赁费用是:");
            if (a3>7&&a3<=30){
              System.out.println(c2.getRent()*a3*0.9+"元");
            }else if(a3>30&&a3<=150){
              System.out.println(c2.getRent()*a3*0.8+"元");
            }else {
              System.out.println(c2.getRent()*a3*0.7+"元");
            }
          }else {//x6
            System.out.println("请选择你要租赁的天数");
            double a3=sc.nextInt();
            System.out.println("分配给您的汽车牌号是:"+c1.getLicensePlate());
            System.out.print("您需要支付的租赁费用是:");
            if (a3>7&&a3<=30){

              System.out.println(c1.getRent()*a3*0.8+"元");
            }else {
              System.out.println(c1.getRent()*a3*0.7+"元");
            }
          }
        }else {//别克
          System.out.println("请选择你要租赁的汽车类型:1、林荫大道 2、GL8");
          String a2=sc.next();
          if (a2.equals("2")){//GL8
            System.out.println("请选择你要租赁的天数");
            double a3=sc.nextInt();
            System.out.println("分配给您的汽车牌号是:"+c4.getLicensePlate());
            System.out.print("您需要支付的租赁费用是:");
            if (a3>7&&a3<=30){
              System.out.println(c4.getRent()*a3*0.9+"元");
            }else if(a3>30&&a3<=150){
