多线程到达，最后一个应该做处理
问题描述：
我正在实现一个日志记录，其中多个线程可以写入一个List日志.最后一个线程应将List的内容写入文件.因此，最后写入List的线程应将List刷新到文件中.最好的方法是什么?
I'm implementing a logging where multiple threads can write into one List of log. The last thread should write the contents of the List to a file. So the thread which is the last to write into the List should flush the List into a file. What is the best way to accomplish this?
对于List，我只需要对多个作者和一个读者有效的并发类之一.
For the List I just need one of the concurrent classes that is efficient for multiple writers and one reader.
答
对于我来说，简单的解决方案是实现Closeable，然后使用close方法进行刷新.
In my case the simple solution was to implement Closeable and then do the flushing in the close method.
