计时器与ScheduledExecutorService调度 [英] Timer vs. ScheduledExecutorService scheduling

问题描述

ScheduledExecutorService 可以直接替换Timer 类，已经在众多 StackOverflow 主题中进行了讨论:

One of the recommended uses of the ScheduledExecutorService is as a direct replacement for the Timer class, as discussed in numerous StackOverflow topics already:

• Java Timer与ExecutorService?
• TimerTask与Executors.newScheduledThreadPool(1)之间的区别
• schedule和scheduleAtFixedRate有什么区别?
• Android计时器时间表与scheduleAtFixedRate

但是， ScheduledExecutorService 和 Timer 支持的方法的命名约定不同.例如，尽管它们都具有 scheduleAtFixedRate()方法，但是Timer方法

However, the naming conventions of the methods supported by ScheduledExecutorService and Timer, are not identical. For example, whereas they both have a scheduleAtFixedRate() method, the Timer method

• 时间表(TimerTask任务，延迟长，时间长)

没有同名对手.

是 ScheduledExecutorService 方法

• scheduleWithFixedDelay(可运行命令，长initialDelay，长延迟，TimeUnit单位)

要代替的那个?

推荐答案

创建并执行一个周期性的操作，该操作首先被启用在给定的初始延迟之后，然后在给定的延迟之后在终止执行与开始执行之间接下来.

Creates and executes a periodic action that becomes enabled first after the given initial delay, and subsequently with the given delay between the termination of one execution and the commencement of the next.

https://docs.oracle.com/javase/7/docs/api/java/util/Timer.html#schedule(java.util.TimerTask，％20long，％20long)

计划指定的任务以重复执行固定延迟，在指定的延迟后开始.随后执行死刑大约每隔固定的时间间隔，即按指定的时间间隔.

Schedules the specified task for repeated fixed-delay execution, beginning after the specified delay. Subsequent executions take place at approximately regular intervals separated by the specified period.

我会说-是;-)
