Running 2 threads simultaneously
提问by lamsaitat
In the case of an IM client. I have made 2 separate threads to handle sending packets (by std io) and receiving packets. The question is how to make these 2 threads run simultaneously so that I can keep prompting for input while at the same time be ready to receive packets at any time?
在 IM 客户端的情况下。我制作了 2 个单独的线程来处理发送数据包（通过 std io）和接收数据包。问题是如何让这两个线程同时运行，以便我可以不断提示输入，同时随时准备接收数据包？
I have already tried setting a timer but the data is always lost receiving.
我已经尝试设置一个计时器，但数据总是丢失接收。

I think you might have missed something significant with either Threads, Streams or both :-)
我认为您可能错过了线程、流或两者的重要内容:-)
You can start a new thread like this:
您可以像这样开始一个新线程：
myThread.start();
The thread will be started and the run() method will be executed automatically by the jvm.
线程将被启动并且 run() 方法将由 jvm 自动执行。
If the threads run-method is reading from a Stream, and it is the only one reading, it will not "miss" anything in that stream.
如果线程 run-method 正在从 Stream 中读取，并且它是唯一的读取，则它不会“错过”该流中的任何内容。

Without more details, it is hard to give a complete answer. Nevertheless, here is the code for starting two threads:
没有更多的细节，很难给出完整的答案。不过，这里是启动两个线程的代码：
Thread thread1 = new Thread () {
public void run () {
// ... your code here
}
};
Thread thread2 = new Thread () {
public void run () {
// ... your code here
}
};
thread1.start();
thread2.start();

Well, they won't run simultaneouslyunless you have a multiprocessor computer, but that's not usually the issue. What will happen is that each thread will get a slice of time, more or less alternatively.
好吧，除非您有一台多处理器计算机，否则它们不会同时运行，但这通常不是问题。将会发生的是，每个线程或多或少都会获得一段时间。
If you're losing I/O, it's probably not the threading that's your real problem. can you tell us how you're reading this stuff?
如果您正在丢失 I/O，那么您真正的问题可能不是线程。你能告诉我们你是如何阅读这些东西的吗？
