1. Application Scenarios for the futureIn concurrent programming, we often use non-blocking models, in the previous multi-threaded three implementations, whether inheriting the thread class or implementing the Runnable interface, there is no guarantee to get to the previous execution results. By implementing the callback interface and using the future to receive multi-threaded execution results.The future r

With executors, you can create different thread pools, some of which are commonly listed in the following table, and some of them may be. In practical applications, personal feelings primarily use newcachedthreadpook and newfixedthreadpool to create thread pools.Executors Create line Cheng code///Call the Newcachedthreadpool method, you can create a buffer t

The reason for the emergence of callable and futureThere are 2 ways to create threads, one is to inherit the thread directly, and the other is to implement the Runnable interface.One drawback to all 2 of these approaches is that you cannot get the results of the execution after the task has been completed.If you need to get the results of execution, you have to use shared variables or the way you use thread communication to achieve the effect, which is more troublesome.Since the beginning of Jav

Then on a continuation of the contract and the study, this article describes the callable and future, they are very interesting, one produces results, one to get results.Callable interface is similar to runnable, can be seen from the name, but Runnable will not return results, and can not be thrown to return the result of the exception, and callable more powerful, after being executed by the thread can return a value, this return value can be obtained

In the previous blog, we introduced the design idea and implementation of the future design pattern, and today we'll talk about how to implement the original package using the JDK.The built-in future of the JDK is mainly used in the callable interface and the Futuretask class.Callable are similar to runnable interfaces, classes that implement callable interfaces, and classes that implement runnable, are tas

XFS: The future of Linux file systems in Big data environments? XFS developer Dave Chinner recently claimed that he believes more users should consider XFS. XFS is often considered to be a file system for users with huge amounts of data, and the scalability of space allocation is "several orders of magnitude" faster than EXT4. Metadata validation means that metadata is self-describing, protecting the file system from being written in the wrong directi

The future is also a Java 1.5 brought in the product, but in the past so many years the actual code has little direct contact, about it is hidden in a variety of out-of-the-box framework silently serve us. The future itself does not represent multi-threading, but rather represents the result of an asynchronous computation, one that will be expected later, as far as the real result is unknown. Before you wan

Baidu on the proposal of SEO wrote: SEO can help the site's high-quality content to better present to search engines, SEO and search engines, is a benign symbiotic relationship. This is true for Seoer, who aims to promote the user experience, however, the rankings of some websites that are currently flooded on the Internet are still based on grey caps or black hat SEO methods. and Baidu to protect its core interests as the starting point, it is not possible to allow a large number of Internet op

Java.util.concurrent.Future is a Java-provided interface that represents the state of asynchronous execution, and the Get method of the future will determine whether the task is completed or not, and if it completes, it will block the thread until the task is complete.Java Futuretask.get () public V get () throws Interruptedexception, executionexception { int s = State; if (s Netty extends the future
