List 集合 找出最小值 和 最大 值

import java.util.*;
class Peng{  
    public static void main(String args[])
     {        //Double[] num = { 45.1,45.2 };
              List dlist=new ArrayList();
              dlist.add(45.1);
              dlist.add(45.2);
              dlist.add(110.22);
              Double max = (Double)dlist.get(0);    
              Double min = (Double)dlist.get(0);
            for (int i = 0; i < dlist.size(); i++) {         
                      if (min > (Double)dlist.get(i)) min = (Double)dlist.get(i);  
                       if (max < (Double)dlist.get(i)) max = (Double)dlist.get(i);       
               }       
                        System.out.println("max的值為" + max + "min的值為" + min);   
      }
}
