释放双眼,带上耳机,听听看~!

总共5个类:
第1个类:Car

package DaDaRentCar;
//父类
public class Car {
     String name; //车名
     int money;  //租金
     int count;  //载人数
     int height; //载货量

}

第2个类:goodCar

package DaDaRentCar;
//只能载货的车
public class goodCar extends Car {

    public goodCar(String string, int i, int j) {
        // TODO Auto-generated constructor stub
        this.name=string;
        this.money=i;
        this.height=j;
    }

}

第3个类:peopleCar

package DaDaRentCar;
//只能载人的车
public class peopleCar extends Car {

        this.name=string;
        this.money=i;
        this.count=j;
    }   
}

第4个类:peoplegoodCar
