Is it OK for multiple threads to use the same PrintWriter concurrently?

好问题。我只是想确保I / O系统不会被混淆。如果两个线程的输出交织在一起就没关系。

Good question. I just want to make sure the I/O system won''t get confused. It''s OK if the output of the two threads is intertwined.

你是否介意单词或单词中的字符是否混合？ 线程1试图打印线程1 ABCDEF 线程2试图打印线程2 GHIJKLM 以下是OK ？ " TThhr 1 eadAe 2a GHd ABCIJKLMDEF" 我认为您应该同步实际的IO调用。我们所做的是利用一个 消息队列; 不同的线程丢弃队列中的消息对象，而低优先级的线程等待<队列中的，弹出消息，执行IO，然后等待下一个 消息。因此只有一个低优先级的线程实际上正在执行IO。 Jeff Schwab < JE ****** @ comcast>在消息中写道 news：eu ******************** @ comcast ... Do you mind if characters within words or words are mixed? Thread 1 trys to print "Thread 1 ABCDEF" Thread 2 trys to print "Thread 2 GHIJKLM" Is the following OK? "TThhr 1 eadAe 2a GHd ABCIJKLMDEF" I think you should synchronize the actual IO call. What we do is utilize a message queue; the different threads drop message objects in the queue while a low-priority thread waits on the queue, pops off a message, does the IO, then waits for the next message. So only one, low-priority, thread is actually doing the IO. "Jeff Schwab" <je******@comcast> wrote in message news:eu********************@comcast...
