List遍历 删除元素

用遍历删除名称遍历的List会发生变化所会报错

//遍历List
for (SaleOutletDetail outletDetail : detailList) {
     Iterator<SaleStraightOutDetail> it = straightOutList.iterator();
     while (it.hasNext()) {
        SaleStraightOutDetail saleStraightOutDetail = it.next();
        if (outletDetail.getUserNo().equals(saleStraightOutDetail.getUserNo())) {
            it.remove();
        }
     }
 }
