Java 8的CompletableFuture API提供了名为thenCompose的方法，它就是专门为这一目的而设计的，thenCompose方法允许你对两个异步操作进行流水线，第一个操作完成时，将其结果作为参数传递给第二个操作。换句话说，你可以创建两个CompletableFutures对象，对第一个CompletableFuture对象调用thenCompose，并向其传递一个函数。当...

CompletableFuturein Java 8 is a huge step forward. From tiny, thin abstraction over asynchronous task to full-blown, functional, feature rich utility. However after few days of playing with it I found few minor disadvantages: CompletableFuture.allOf()returningCompletableFuture<Void>discussed earlier....
Suppose you want to execute some code that queries a database so the code is executed in a separate thread and then trigger the printing of the query result when it is available. Using a well-known pattern introduced in Java 5, you could wrap the task to

CompletableFuture是java8引入的一个异步类,它最大的优势是可以在创建的对象中传入一个回调对象,在任务结束后(done或throw exception),自动调用回调对象的回调方法,而不用让主线程阻塞。 多任务并行协作 假如我们要做咖啡,有3个子任务可以并行执行:洗杯子、磨咖啡、烧水,这3步完成后,我们开始泡咖啡。这种需求我们一...
Java has seen a major shift towards functional programming paradigms. One of the features introduced in Java 8 is CompletableFuture, which provides a flexible way to work with asynchronous computations. CompletableFuture allows developers to chain and combine multiple asynchronous tasks in a more concis...
CompletableFuture , which was introduced in Java 8, provides an easy way to write asynchronous, non-blocking, and multi-threaded code.
