    for (i in 1..5) {

Java线程池：ExecutorService，Executors_executorservice线程池_zhangphil的博客-CSDN博客简单的Java线程池可以从Executors.newFixedThreadPool( int n)获得。此方法返回一个线程容量为n的线程池。然后ExecutorService的execute执行之。现给出一个示例。package zhangphil.executorservice;import java.util.concurrent.ExecutorService;import j_executorservice线程池https://blog.csdn.net/zhangphil/article/details/43898637ScheduledThreadPoolExecutor周期性执行线程任务scheduleAtFixedRate_zhangphil的博客-CSDN博客ScheduledThreadPoolExecutor周期性执行线程任务scheduleAtFixedRate ScheduledThreadPoolExecutor mScheduledThreadPoolExecutor = new ScheduledThreadPoolExecutor(1); mScheduledThreadPoolExecutor.sched...https://blog.csdn.net/zhangphil/article/details/80735215
