java迭代的几种方式(补充中...)

一、for()循环
List list = query.list();//返回的是list,list里面存的是Student对象
for (int i=0;i<list.size(); i++)
{
    Student stu = (Student)list.get(i);
    System.out.println(stu.getName());
}
二、迭代循环
for (Iterator iter = list.iterator(); iter.hasNext();) {
    Object[] record = (Object[]) iter.next();
    System.out.print(record[0] + "---" + record[1]);
}
