JAVA List<Object[]>取值问题

//test 2020-12-2 10:24:34 by kaspar
String hql444 = "select sum(collectionPrice),sum(factPrice) from ProcessingCollectionList where processingOrderNumber='"+bean.getProcessingOrderNumber()+"' and collectionPrice != null ";
List list444 = baseDao.findByHQL(hql444.toString());

System.out.println(list444.get(0));
List list = new ArrayList();
if(list444!= null && list444.size()>0 )
{
Object[] tempObj = (Object[]) list444.get(0);
System.out.println("数值一" + tempObj[0] + "————" + "数值二" + tempObj[1] );
} 
//test

三种遍历方法：
一：采用
for(int i = 0 ; i Object[] tempObj = objListstaff.get(i);
system.out.print("技术部" + tempObj[0] + "————" + "销售部" + tempObj[1] );

二：采用迭代器

for (Iterator iterator = objListstaff.iterator(); iterator.hasNext();) {
Object[] tempObj = ( Object[]) iterator.next();
system.out.print("技术部" + tempObj[0] + "————" + "销售部" + tempObj[1] );

三：采用foreach循环
for(Object[] tempObj : objListstaff){
system.out.print("技术部" + tempObj[0] + "————" + "销售部" + tempObj[1] );
