| 這陣子在研究CompletableFuture時，剛好看到一篇Oracle關於CompletableFuture如何使用才能有好效能的投影片。我在這裡做了些整理，分享給大家；如果有理解有問題或不足的地方，希望大家可以幫忙更正或補充。本篇圖片都來自於Reference中的投影片。本篇說到五個重點，前四點我會分別說明；第五點如字面上所說，ThreadPool本來就要根據需求而去使用，這裡我不特別探討。 | 這陣子在研究CompletableFuture時，剛好看到一篇Oracle關於CompletableFuture如何使用才能有好效能的投影片。我在這裡做了些整理，分享給大家；如果有理解有問題或不足的地方，希望大家可以幫忙更正或補充。本篇圖片都來自於Reference中的投影片。本篇說到五個重點，前四點我會分別說明；第五點如字面上所說，ThreadPool本來就要根據需求而去使用，這裡我不特別探討。 | ||
