取出List<Integer>中的数据

以下是数据层的方法：

@Override
 public List<Integer> countTrainDemandPublish(String queryFromTime, String queryToTime) {
  StringBuffer sbHql = new StringBuffer();
  List<Integer> aList = null;
  Query query = null;
  sbHql.append("select count(t1.ifProductKnowhow), ");
  sbHql.append("count(t1.ifSellingSkills), ");
  sbHql.append("count(t1.ifMindestConstruction), ");
  sbHql.append("count(t1.ifCustomerDevelopment), ");
  sbHql.append("count(t1.ifContractOfKnowledge), ");
  sbHql.append("count(t1.ifMeaningUsageInsurance), ");
  sbHql.append("count(t1.ifOthers) ");
  sbHql.append("from CourseDemandPublish t1");
  sbHql.append(" where 1=1");
  SimpleDateFormat df1 = new SimpleDateFormat("yyyy-MM-dd");
  if (queryFromTime!=null && !"".equals(queryFromTime.trim()) && queryToTime!=null && !"".equals(queryToTime.trim())) {
   sbHql.append(" and (t1.updateDate >=:sortDate ");
   sbHql.append(" or t1.updateDate <=:sortEndDate) ");
   query = getSession().createQuery(sbHql.toString());
   
   try {
    java.util.Date date1 = df1.parse( queryFromTime );
    java.util.Date date2 = df1.parse( queryToTime );
    query.setParameter("sortDate", date1);
    query.setParameter("sortEndDate", date2);
    System.out.println(date1);
   } catch (ParseException e) {
    e.printStackTrace();
   }
   aList = (ArrayList<Integer>) query.list();
  }else if(queryFromTime!=null && !"".equals(queryFromTime.trim())){
   sbHql.append(" and t1.updateDate >=:sortDate ");
   query = getSession().createQuery(sbHql.toString());
   try {
    java.util.Date date1 = df1.parse( queryFromTime );
    query.setParameter("sortDate", date1);
    System.out.println(date1);
   } catch (ParseException e) {
    e.printStackTrace();
   }
   aList = (ArrayList<Integer>) query.list();
  }else if(queryToTime!=null && !"".equals(queryToTime.trim())){
   sbHql.append(" and t1.updateDate <=:sortEndDate ");
   query = getSession().createQuery(sbHql.toString());
   try {
    java.util.Date date1 = df1.parse( queryToTime + "23:59:59" );
    query.setParameter("sortEndDate", date1);
    System.out.println(date1);
   } catch (ParseException e) {
    e.printStackTrace();
   }
   aList = (ArrayList<Integer>) query.list();
  }
  else{
   query = getSession().createQuery(sbHql.toString());
   aList = (ArrayList<Integer>) query.list();
  }
  return aList;
 }
下面将取出数据：

//结果列表
  List<Integer> aList = trainDemandGatherSev.countTrainDemandPublish(
    queryFromTime,
    queryToTime);

Object[] tObject =  null ;

for(Object obj1:aList){

  tObject = (Object[])obj1;

}

for (int i=0 ; i < tObject.length ; i++){

    Integer tInteger = Integer.parseInt(tObject[i].toString()) ;

}
