如何用Stream重构它

Question

如何用java流重构它？

List<SessionCreateParams.LineItem> elements = new ArrayList<>();
SessionCreateParams.LineItem lineItem;
for (Product product : experience.getProducts()) {
String taxRate = getTaxRate(product.getPriceId());
lineItem = stripeProxy.createLineItem(1L, product.getPriceId(), taxRate);
elements.add(lineItem);
}

Answer 1

对产品进行流式传输，将每个产品转换为LineItem并收集为List。

List<SessionCreateParams.LineItem> elements =
experience.getProducts()
.stream()
.map(p -> stripeProxy.createLineItem(1L, p.getPriceId(), 
getTaxRate(p.getPriceId())))
.collect(Collectors.toList());
