list<delipromotionnode> delipromotionnodechildren = delipromotionnode.getchildren(); for (int i = 0; i < delipromotionnodechildren.size(); i++) { delipromotionnode promotionnode = delipromotionnodechildren.get(0); integer paymentdays = promotionnode.getpolicyinfo().getpaymentdays(); if (deliariesaccounttimerule.delivery_time.equals(data.getaccounttimerule()) && null == paymentdays) { throw pamirsexception.construct(deliariespromotionexpenumerate.biz_error).setmsg("记账时间规则为按发货时间结算，指定账期天数必填").errthrow(); } } 优化这段代码
为了优化这段代码，我注意到以下几点可以改进： 1. 避免在循环中多次调用`delipromotionnodechildren.size()`方法。可以先将该方法的结果存储在一个变量中，然后在循环条件中使用该变量。 2. 在循环中，每次都使用`delipromotionnodechildren.get(0)`来获取元素并赋值给`promotionnode`。这会导致每次都获取第一个元素。如果想要遍历所有的元素，应该使用`delipromotionnodechildren.get(i)`来获取元素。 3. 在循环内部，每次都调用`promotionnode.getpolicyinfo().getpaymentdays()`来获取`paymentdays`的值。可以将该值存储在一个变量中，以减少方法调用。 下面是优化后的代码示例： ```java List<delipromotionnode> delipromotionnodechildren = delipromotionnode.getchildren(); int size = delipromotionnodechildren.size(); for (int i = 0; i < size; i++) { delipromotionnode promotionnode = delipromotionnodechildren.get(i); Integer paymentdays = promotionnode.getpolicyinfo().getpaymentdays(); if (deliariesaccounttimerule.delivery_time.equals(data.getaccounttimerule()) && null == paymentdays) { throw pamirsexception.construct(deliariespromotionexpenumerate.biz_error).setmsg("记账时间规则为按发货时间结算，指定账期天数必填").errthrow(); } } ``` 优化建议： 1. 存储列表大小的变量可以提高循环性能。 2. 在循环中正确遍历所有元素。 3. 使用变量存储`paymentdays`的值，以减少方法调用次数。 [2024-12-23 00:19:23 | AI写代码神器 | 863点数解答]
