java JUC线程池：Executors.newSingleThreadExecutor代码示例

package com.zxl.juc;

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


public class SingleThreadExecutorDemo1 {
    public static void main(String[] args) {
        ExecutorService executorService = Executors.newSingleThreadExecutor();
        for (int i = 0; i < 5; i++) {
            int j=i;
            executorService.submit(()->{
                System.out.println(Thread.currentThread().getName()+"=="+j);
            });
        }
        executorService.shutdown();
    }
}

输出：

pool-1-thread-1==0
pool-1-thread-1==1
pool-1-thread-1==2
pool-1-thread-1==3
pool-1-thread-1==4
