ScheduledthreadPool（）函数可以多次使用？它会对线程的处理产生影响吗？ [英] ScheduledthreadPool() function can be used multiple times? will it make difference in the processing of threads

问题描述

 scheduledThreadPool = Executors.newScheduledThreadPool（Runtime.getRuntime（）。availableProcessors（））; 
 
 scheduledThreadPool1 = Executors.newScheduledThreadPool（Runtime.getRuntime（）。availableProcessors（））; 
 
  while （mNumberOfChatToGenerate！= 0）{
 WebChatTask chatWork =  new  WebChatTask（mConfig，chatId ++）; 
 System.out.println（ 当前延迟： + mCurrDelay）; 
 scheduledThreadPool.schedule（chatWork，mCurrDelay * chatId，TimeUnit.SECONDS）; 
 
 mNumberOfChatToGenerate--; 
 
 WebChatTask chatWork1 =  new  WebChatTask（mConfig，chatId ++）; 
 scheduledThreadPool1.schedule（chatWork1，mCurrDelay * chatId，TimeUnit.SECONDS）; 
 mNumberOfChatToGenerate--; 
} 

解决方案

你一遍又一遍地创建 WebchatTask 。

使用 ScheduledThreadPool 是一个概念，让相同的 Thread 一遍又一遍地运行再次。

所以这不是一个好例子。



你想用这个做什么？



参见示例： http://tutorials.jenkov.com/java- util-concurrent / scheduledexecutorservice.html [ ^ ]

scheduledThreadPool = Executors.newScheduledThreadPool(Runtime.getRuntime().availableProcessors());

scheduledThreadPool1 = Executors.newScheduledThreadPool(Runtime.getRuntime().availableProcessors());

while(mNumberOfChatToGenerate!=0){
  WebChatTask chatWork = new WebChatTask(mConfig,chatId++); 
  System.out.println("Current delay : " + mCurrDelay);
            scheduledThreadPool.schedule(chatWork, mCurrDelay * chatId, TimeUnit.SECONDS);

  mNumberOfChatToGenerate--;

  WebChatTask chatWork1 = new WebChatTask(mConfig,chatId++); 
  scheduledThreadPool1.schedule(chatWork1, mCurrDelay * chatId, TimeUnit.SECONDS);
  mNumberOfChatToGenerate--;
}

解决方案

you are creating WebchatTask over and over again.
Using a ScheduledThreadPool is a concept to let the same Thread run over and over again.
So this is not a good example.

What do you want to do with this?
