对一个类中创建的一组对象进行操作

public class Shuzuduixiangxingwei {
   private int size;
   private String name;
   
   public int getSize(){
       return size;
   }
   public void setSize(int x){
       size = x;
   }
   public static void main(String[] args){
       Shuzuduixiangxingwei[] pets = new Shuzuduixiangxingwei[3];
       pets[0] = new Shuzuduixiangxingwei();
       pets[1] = new Shuzuduixiangxingwei();
       pets[2] = new Shuzuduixiangxingwei();
       
       for(int i=0 ;i<3;++i){
           pets[i].setSize(10+3*i);
       }
       for(int i=0;i<3;++i){
           System.out.println("狗狗"+i+"的size是："+pets[i].getSize());
       }
   }
}
