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
在Java的开发过程中,程序员常常会遇到各种各样的错误和警告。其中之一是“All illegal access operations will be denied in a future release”。这一提示主要是因为Java在尝试访问某些模块或者类时,违反了强封装原则。这通常与Java模块系统(JPMS)相关。
To simplify monitoring, debugging, and tracking, all generated asynchronous tasks are instances of the marker interface AsynchronousCompletionTask. Operations with time-delays can use adapter methods defined in this class, for example: supplyAsync(supplier, delayedExecutor(timeout, timeUnit)). To ...
