如何正确传值呢求指点谢谢啦~~

//父类

package ThirdEx;

public abstract class One{

   public static int number;
   public static int carMoney;
   public int no;
   public String carName;
   public static int weight;

   public void Aodi() {
       // TODO Auto-generated method stub
       System.out.println(no+"."+"    "+carName+"    "+carMoney+"/day"+"    "+"can carry person:"+number);
   }
   public void Mazida() {
       // TODO Auto-generated method stub
       System.out.println(no+"."+"    "+carName+"    "+carMoney+"/day"+"    "+"can carry person:"+number);
   }
   public void PiKaxue() {
       // TODO Auto-generated method stub
       System.out.println(no+"."+"    "+carName+"    "+carMoney+"/day"+"    "+"can carry person:"+number+"    "+"can carry weight:"+weight+"t");
   }
   public void JinLong() {
       // TODO Auto-generated method stub
       System.out.println(no+"."+"    "+carName+"    "+carMoney+"/day"+"    "+"can carry person:"+number);
   }
   public void SongHuaJiang() {
       // TODO Auto-generated method stub
       System.out.println(no+"."+"    "+carName+"    "+carMoney+"/day"+"    "+"can carry weight:"+weight+"t");
   }
   public void YiWeiHe() {
       // TODO Auto-generated method stub
       System.out.println(no+"."+"    "+carName+"    "+carMoney+"/day"+"    "+"can carry weight:"+weight+"t");
   }
}

//Aodi类

package ThirdEx;

public class Aodi extends One {
   public Aodi(){
         no = 1;
       carName = "Aodi";
       carMoney = 500;
       number = 4;
   }
}

//Mazida类

package ThirdEx;

public class Mazida extends One {
   public Mazida(){
        no=2;
       carName="Mazida";
       carMoney=400;
       number=4;
   }
}

//PiKaxue类

package ThirdEx;

public class PiKaxue extends One {
   public PiKaxue(){
       no=3;
       carName="PiKaxue";
       carMoney=450;
       number=4;
       weight=2;
   }
}

还有其他车的类都一样的写法就不贴上来了

//测试类
