java编程 汽车与汽车厂

唉看这份上30分我要了.....
类一如下
public class CarModel
{
private String style,color,category;
public CarModel(){}
public CarModel(String a,String b,String c)
{
this.style=a;
this.color=b;
this.category=c;
}
public String getStyle()
{
return this.style;
}
public String getColor()
{
return this.color;
}
public String getCategory()
{
return this.category;
}
}
/////////////////////////////////////

public class CarManufactory
{
private Static java.util.ArrayList list=null;
public ArrayList getList()
{
if(list==null)
{
this.list =new java.util.ArrayList();
return this.list;
}
else
{
return this.list;
}
}

public void setCar(String a,String b,String c)
{
CarModel car=new CarModel(a,b,c);
this.getList().add(car);
}
public void getCar()
{
for(int i=0;i.list.size();i++)
{
CarModel car=(CarModel) this.list.get(i);
System.out.println("car"+i+": style is:"+car.getStyle()+" color is:"+car.getColor()+" category is:"+car.getCategory());
}
}
}

好了拿分来..主要方法都写要了...要是你不会调用我不负责任啊..
自己在写个main方法调用吧...

分太少，题目很简单

是上机题目吧,比较简单的,还是自己学下吧,不然以后就后悔了!
