Java入门第二季6-1综合练习

获取租用车名称及总容量那块写的有点问题,看了下大家都用的数组.先放上来,稍后再完善

汽车抽象类
public abstract class Car {
public int carNumber;
public String carName;
public int carMoney;
public int carCapacity1man;
public int carCapacity2goods;
public abstract void getCar();
}

载人子类
public class MannedCar extends Car {
public void getCar() {
System.out.println(carNumber+carName+carMoney+"元/天"+"载人:"+carCapacity1man+"人");
}
}

货车子类
public class Van extends Car {
public void getCar() {
System.out.println(carNumber+carName+carMoney+"元/天"+"载货:"+carCapacity2goods+"吨");
}
}

皮卡子类
public class PickupTruck extends Car{
public void getCar() {
System.out.println(carNumber+carName+carMoney+"元/天"+"载人:"+carCapacity1man+"人"+"载货:"+carCapacity2goods+"吨");
}
}

主函数
public class main {

public static void main(String[] args) {

    MannedCar car1 = new MannedCar();
    car1.carNumber = 1;
    car1.carName = "奥迪A6";

    car1.carCapacity1man = 4;

    MannedCar car2 = new MannedCar();
    car2.carNumber = 2;
    car2.carName = "马自达6";
    car2.carMoney = 400;
    car2.carCapacity1man = 4;

    PickupTruck car3 = new PickupTruck();
    car3.carNumber = 3;
    car3.carName = "皮卡雪6";
    car3.carMoney = 450;
    car3.carCapacity1man = 4;
    car3.carCapacity2goods = 2;

    MannedCar car4 = new MannedCar();
    car4.carNumber = 4;
    car4.carName = "金龙";
    car4.carMoney = 800;
    car4.carCapacity1man = 20;

    Van car5 = new Van();
    car5.carNumber = 5;
    car5.carName = "松花江";
    car5.carMoney = 400;
    car5.carCapacity2goods = 4;

    Van car6 = new Van();
    car6.carNumber = 6;
    car6.carName = "依维柯";
    car6.carMoney = 1000;
    car6.carCapacity2goods = 20;
