如何獲取 for 循環中所有項目的總金額？

Question

我有 6 個訂單。 我循環了 6 個訂單以獲得每個訂單的總價。

我想要做的是在循環中添加每個訂單的總價格，然后將其與authorized amount進行比較。

假設授權金額為 2000 。

發生的情況是將授權金額與 PER ORDER TOTAL PRICE 進行比較，而不是ALL ORDERS TOTAL PRICE 。

這是一個示例代碼：

for (Entity checkout : checkouts) {
                List<Entity> selectedJOs = AppUtil.getEntities(AppUtil.getListIds(checkout, "job-orders"), jobOrders);
                long finalGrandTotalAmount = 0;

                for (Entity job_order : selectedJOs) {

                    grandTotalAmount = 0;
                    long totalJobOrderPurchasedAmount = 0;
                    long totalJobOrderDeliveryFee = 0;
                    long totalJobOrderShoppingFee = 0;
                    long totalJobOrderDiscount = 0;
                    totalJobOrderRecalled = 0;
                    long totalCampaignDiscount = 0;

                    if (!job_order.attributes.status.equals("cancelled")) {
                        totalJobOrderPurchasedAmount += (job_order.attributes.purchased_deliverables_amount_in_cents + job_order.attributes.non_membership_fee_in_cents);
                        totalJobOrderDeliveryFee += job_order.attributes.delivery_fee_in_cents;
                        totalJobOrderShoppingFee += job_order.attributes.shopping_fee_in_cents;
                        totalJobOrderRecalled += job_order.attributes.recalled_deliverables_amount_in_cents;

                        List<Entity> selectedCampaigns = AppUtil.getEntities(AppUtil.getListIds(job_order, "job-order-fmcg-campaign-vouchers"), campaignDiscounts);


                        for (Entity campaignDiscount : selectedCampaigns) {
                            totalCampaignDiscount += campaignDiscount.attributes.discount_in_cents;

                        }
                        for (Entity discount : discounts) {
                            long job_order_discount;

                            if (discount.relationships.job_order.data.id.equals(job_order.id)) {
                                long purchase_amount = job_order.attributes.purchased_deliverables_amount_in_cents;
                                if (discount.attributes.sum_in_cents_off <= 0) {
                                    job_order_discount = Math.round(purchase_amount * discount.attributes.percent_off);
                                } else {
                                    job_order_discount = discount.attributes.sum_in_cents_off;
                                }

                                totalJobOrderDiscount += job_order_discount;
                            }
                        }


                        long discounts_total = totalJobOrderDiscount > 0 ? totalJobOrderDiscount + totalCampaignDiscount : totalCampaignDiscount;
                        grandTotalAmount = (totalJobOrderPurchasedAmount - discounts_total) + (totalJobOrderShoppingFee + totalJobOrderDeliveryFee) - job_order.attributes.credit_amount_of_cents;

                        boolean isLoginPrimary = true;

                        List<Entity> selected_consignments = AppUtil.getEntities(AppUtil.getListIds(job_order, "consignments"), consignments);

                        for (Entity consignment : selected_consignments) {
                            if (consignment.attributes.primary) {
                                Entity user = AppUtil.getEntity(consignment.relationships.user.data.id, users);
                                isLoginPrimary = user.relationships.profile.data.type.equals("runner-profiles") && user.id.equals(Preferences.getString(Prefkey.session_user_id)) && isLoginPrimary;
                            }
                        }

                        if (job_order.relationships.completed_by_user.data != null) {
                            if (job_order.relationships.completed_by_user.data.id.equals(Preferences.getString(Prefkey.session_user_id))) {
                                if (checkout.attributes.payment_mode.equals("credit-card")) {
                                    if (checkout.attributes.authorized_amount_in_cents < grandTotalAmount) {
                                        grandTotalAmountCc += checkout.attributes.authorized_amount_in_cents - totalJobOrderRecalled;
                                        grandTotalAmountCash += checkout.attributes.paid_cash_difference_in_cents;
                                    } else {
                                        grandTotalAmountCc += grandTotalAmount - totalJobOrderRecalled;
                                        grandTotalAmountCash += 0;
                                    }

                                    grandTotalAmountCash += grandTotalAmount - totalJobOrderRecalled;
                                }
                            }
                        }
                    }
                }

            }

對於每個循環，您都在重置 grandTotalAmount。 通過使其全球化，將解決您的問題。
