CompletableFuture简单使用

开四个线程，异步+并行地从远端获取结果，然后解析，放入集合

List<Integer> priceList = new ArrayList(4);

CompletableFuture.supplyAsync(() -> this.getPriceFromRemote()).thenAccept(result -> priceList.add(this.parsePrice(result)));
CompletableFuture.supplyAsync(() -> this.getPriceFromRemote()).thenAccept(result -> priceList.add(this.parsePrice(result)));
CompletableFuture.supplyAsync(() -> this.getPriceFromRemote()).thenAccept(result -> priceList.add(this.parsePrice(result)));
CompletableFuture.supplyAsync(() -> this.getPriceFromRemote()).thenAccept(result -> priceList.add(this.parsePrice(result)));
