java线程池(newSingleThreadExecutor())小应用

  创建单个线程,用来操作一个无界的队列任务,不会使用额外的线程。如果线程崩溃会重新创建一个,直到任务完成。

  代码:

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

public class Threadd2 {

    public static void main(String[] args) {
        ExecutorService es = Executors.newSingleThreadExecutor();
        run command = new run();
        es.execute(command);
        es.execute(command);
        es.shutdown();
    }
    
    
}

class run implements Runnable{

    @Override
    public void run() {
        // TODO Auto-generated method stub
        try {
            Thread.sleep(100);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        System.out.println(Thread.currentThread().getName());
    }
    
}

  输出结果:pool-1-thread-1
       pool-1-thread-1
