hibernate中使用sql语句进行表链接查询，对结果集的遍历方法

List<Course_Material> list = new ArrayList<Course_Material>();
        @SuppressWarnings("rawtypes")
        List accountList = query.list();
        if(accountList.size()>0)
        {
            Object[] objects;
            Course_Material cm = new Course_Material();
            for(int i=0;i<accountList.size();i++)
            {
                objects = (Object[])accountList.get(i);//将结果集转换成Objects数组
                cm.setNumber(Integer.parseInt(objects[0].toString()));
                cm.setCourseXuhao(Integer.parseInt(objects[1].toString()));
                cm.setCourseName(objects[2].toString());
                cm.setClassName(objects[3].toString());
                cm.setDateType(objects[4].toString());
                cm.setAttachFile(objects[5].toString());
                cm.setAttachName(objects[6].toString());
                list.add(cm);
            }
        }
