What do you mean by finally ? 而无论如何,finally 块的代码最终都会被执行。 As in the end the same code will be executed.ES2018另一振奋人心的特效是finally ()方法。 Another exciting addition to ES2018 is the finally () method. The code inside the finally block is always executed.
在本教程中,我们将研究Java中的finally 关键字的用法。 In this tutorial, we will learn about Final Keyword in Java. Finally 代码块总是执行,无论一个异常是否发生。A finally block of code always executes, whether or not an exception has occurred. 这与同步的finally 之句的行为并不匹配,所以让我们重构它:. That doesn't align with how our synchronous finally clause behaves, so let's refactor:. 无论是否抛出异常,finally 代码块总是会被执行。 Irrespective of whether an exception is thrown or not, the finally block of code will always be executed. Andfinally ,这是一个父子的故事,是他们走向爱和相互接受的几十年旅程。 And finally , it's the story of a father and son and their decades-long journey toward love and mutual acceptance. 下面是一个更加复杂的例子(在同一个try语句里包含except和finally 子句):.

Finally块,确保在finally 块中关闭任何已打开的连接。 Finally blocks, and ensure that you close any open connections within the finally block, Here is a short example:.与then()和catch()相同,finally ()方法总是返回一个promise,因此你可以链接更多的方法。 As with then() and catch(), the finally () method always returns a promise, so you can chain more methods. 通过将对象放入try块中,并在调用finally 块中的Dispose,可以获得相同的结果;. You can achieve the same result by putting the object inside a try block and then calling Dispose in a finally block; 最后值得提的是,finally 块常用来释放资源,比如I/Obuffer,数据库连接等。 Last thing to mention is that the finally block is used to release resources like I/O buffers, database connections, etc. Finally ,enjoythemoment,提前准备好一切,这样你就可以和客人一起度过美好的时光!!Finally , enjoy the moment, prepare everything in advance so you can spend time with your guests and have a fabulous time! 在此代码中,finally ()方法在数据获取处理后直接隐藏了加载spinner。 In this code, the finally () method simply hides the loading spinner after the data is fetched and processed. Finally ,音乐疗法可用于学校提高社会技能和communicationJacobson&Artman,2013)。Finally , music therapy can be used in schools to improve social skills and communication(Jacobson& Artman, 2013). 以下是一个更复杂些的例子(在同一个try语句中的except和finally 子句的工作方式与Python2.5一样)::. A more complicated example(having except and finally clauses in the same try statement works as of Python 2.5):. 否则,当控制到达finally 块的结束点时,将继续对当前异常的处理。 Otherwise, when control reaches the end point of the finally block, processing of the current exception is continued. 现在的编程语言使用新的关键字来处理和捕获异常,其名称为throw、try、finally 和catch等。 The language incorporates new keywords to dispatch and trap exceptions, using names such as throw, try, finally and catch. 添加finally让我们把finally 添加到这种混合结构中,看看如何用Promises使异步操作达到同样的结果。 Let's add finally back into the mix, and see how we can use Promises to achieve the same result for asynchronous operations. Java的异常处理是通过5个关键词来实现的:try、catch、throw、throws和finally 。 For instance, the Java Exception handling done through the following five keywords: try, catch, throw, throws, and finally . 使用finally 块允许你运行您想要执行的任何cleanup-type语句,无论在受保护的代码中发生什么。 Using a finally block, it lets you run any cleanup type statement that you want to execute, no matter what happens in the protected code. BigSean的Facebook官方主页确认他的首张专辑《Finally Famous》将在2010年9月14日发行。 Big Sean's official Facebook page confirmed that his debut album Finally Famous& Consequence's Cons TV would be released on September 14, 2010. 使用finally 块允许你运行您想要执行的任何cleanup-type语句,无论在受保护的代码中发生什么。 Using a finally block allows you to run any cleanup-type statements that you want to execute, no matter what happens in the protected code. 当(如果)控制到达该finally 块的结束点时,控制就转到下一个封闭try语句的finally 块。 When and if control reaches the end point of a finally block, control is transferred to the finally block of the next enclosing try statement. 使用try-finally块的普遍原因是为了保护管理代码的资源,所以珍贵的资源被保证在finally 块中发布。 A common reason for using try-finally blocks is to guard resource managing code, thus guaranteeing the release of precious resources in the finally block. 异常处理使用try、catch和finally 关键字来尝试可能未成功的操作,处理失败,以及在事后清理资源。 Exception handling uses the try, catch, and finally keywords to attempt actions that may not succeed, to handle failures, and to clean up resources afterwards.
