简化这串代码boolean flag = true; if CollectionUtilsisNotEmptylist for DrugBandQuantityPurchaseVO vo list if vogetBatch == batch flag = true;

boolean flag = CollectionUtils.isNotEmpty(list); if (flag) { for (DrugBandQuantityPurchaseVO vo : list) { if (vo.getBatch() != batch){ flag = false; break; } } } return flag;
