答答租车系统(Java课后作业)

一、Car.java(父类)

package com.rentcar;

public class Car {
    private String name;
    private int price;
    private int mancapacity;
    private double goodscapacity;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public void getList(){

    }

    public double getCargo() {
        return goodscapacity;
    }

    public int getPeople() {
        return mancapacity;
    }

    public int getRent() {
        return price;
    }

}

二、 PassengerCar.java(载客子类)

package com.rentcar;

public class PassengeCar extends Car {
    String name;
    int price;
    int mancapacity;

    public PassengeCar(String name,int price,int mancapacity){
        this.name = name;
        this.price = price;
        this.mancapacity = mancapacity;
    }

    public String getName(){
        return name;
    }

    public int getPeople(){
        return mancapacity;
    }

    public int getRent(){
        return price;
    }

    public void getList(){
        System.out.println(name+"\t"+price+"元/天"+"\t"+"载人:"+mancapacity+"人");
    }
}

三、Cargo.java(货车子类)

public class Cargo extends Car {
    String name;
    int price;
    double goodscapacity;

    public Cargo(String name,int price,double goodscapacity){
        this.name = name;
        this.price = price;
        this.goodscapacity = goodscapacity;

    int price;
    int mancapacity;
    int goodscapacity;

    public Pickup(String name,int price,int mancapacity,int goodscapacity){
        this.name = name;
        this.price = price;
        this.mancapacity = mancapacity;
        this.goodscapacity = goodscapacity;
    }

    public String getName(){
        return name;
    }

    public int getPeople(){
        return mancapacity;
    }

    public double getCargo(){
        return goodscapacity;
    }

    public int getRent(){
        return price;
    }

    public void getList(){
        System.out.println(name+"\t"+price+"元/天"+"\t"+"载人:"+mancapacity+"人"+"\t"+"载货"+goodscapacity+"吨");
    }
}

五、Test.java(测试类)

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

public class Test {

    /**
     * @param args
     */
    static Car[] cars = {new PassengeCar("奥迪", 500, 4),

        // TODO Auto-generated method stub

        System.out.println("欢迎使用答答租车系统");
        Isrentcar();//判断并打印租车列表
        int carcount = rentcarCount();//获取租车数量
        int[] carnums = getCarnums(carcount);//获取租车序号列表
        int days = rentcarDay();
        getBill(days,carcount,carnums);
    }

    public static void Isrentcar(){

            y++;
        }
        return rentArray;
    }

    public static int rentcarDay(){
        System.out.println("请输入租车天数:");
        Scanner input4 = new Scanner(System.in);
        int day = input4.nextInt();
        return day;
    }

    public static void getBill(int days,int carcount,int[] carnums){
        int people = 0;
        double cargo = 0;
        int rent = 0;
        System.out.println("您的账单:");
        System.out.println("***可载人的车有:");
        for(int i=0;i<carnums.length;i++){
            if(cars[carnums[i]-1] instanceof PassengeCar || cars[carnums[i]-1] instanceof Pickup){
            System.out.print(cars[carnums[i]-1].getName()+"  ");
            people += cars[carnums[i]-1].getPeople();
            }
        }
        System.out.println("共载人"+people+"人");
        System.out.println("***可载货的车有:");
        for(int i=0;i<carnums.length;i++){
            if(cars[carnums[i]-1] instanceof Cargo || cars[carnums[i]-1] instanceof Pickup){
