对一个类中创建的一组对象进行操作

 1 public class Shuzuduixiangxingwei {
 2    private int size;
 3    private String name;
 4    
 5    public int getSize(){
 6        return size;
 7    }
 8    public void setSize(int x){
 9        size = x;
10    }
11    public static void main(String[] args){
12        Shuzuduixiangxingwei[] pets = new Shuzuduixiangxingwei[3];
13        pets[0] = new Shuzuduixiangxingwei();
14        pets[1] = new Shuzuduixiangxingwei();
15        pets[2] = new Shuzuduixiangxingwei();
16        
17        for(int i=0 ;i<3;++i){
18            pets[i].setSize(10+3*i);
19        }
