如何无限期地暂停Java中的线程并稍后恢复它？

谁说Java不够低级？

这是我的3分钟解决方案。我希望它适合您的需求。

import java.util.ArrayList;import java.util.List;public class ThreadScheduler {    private List<RoundRobinProcess> threadList = new ArrayList<RoundRobinProcess>();    public ThreadScheduler(){        for (int i = 0 ; i < 100 ; i++){ threadList.add(new RoundRobinProcess()); new Thread(threadList.get(i)).start();        }    }    private class RoundRobinProcess implements Runnable{        private final Object lock = new Object();        private volatile boolean suspend = false , stopped = false;        @Override        public void run() { while(!stopped){     while (!suspend){         // do work     }     synchronized (lock){         try {  lock.wait();         } catch (InterruptedException e) {  Thread.currentThread().interrupt();  return;         }     } }        }        public void suspend(){ suspend = true;        }        public void stop(){ suspend = true;stopped = true; synchronized (lock){     lock.notifyAll(); }        }        public void resume(){ suspend = false; synchronized (lock){     lock.notifyAll(); }        }    }}

请注意，“执行工作”不应被阻止。
