Threads<br />
sleep(10000) says that it just can sleep 10 sec if nobody needs it. That is reason why<br />
you do<br />
try{<br />
sleep(10000);<br />
}<br />
catch(InterruptedException x){<br />
//do smth here<br />
}<br />
You just try, it is not an order. It tries but not always sleeps!<br />
Hi, Is there somebody who can tell me why my thread sleeps longer then I told<br />
him to do...<br />
I have a thread that has to sleep for 60000 millesec. But every 4, 5 minutes<br />
it sleeps for 61000 millesec.? I have to built an application that get the<br />
time every minute, but with this sleep I can't trust the java threads.<br />
So can somebody tell me what is going wrong???<br />
Answer: Really JDK never give you warranty that will wake your thread after XXX<br />
ms.<br />
You can be sure only<br />
that your thread will not be waked up before!<br />
For good timing you should take another, better for real time perfomance, VM.<br />
For example PERC from Nemonics.com or something else...<br />
I have created a program with a main method that instantiates and starts three<br />
threads, the first two of which are daemons. Why daemons does die when normal<br />
thread die?<br />
Answer: Because of nature of daemon threads. They are alive if exists at least one<br />
"normal user's" thread. Otherwise they die immediately<br />
Q: Does anyone know if there is a way for two threads to find each other if they<br />
are started in two different JVM?<br />
In other words, I start a thread in one JVM, then I want to PipeWrite to another<br />
Thread that is doing a PipeReader. Any help would be appreciated!<br />
Answer: Use of Piped streams is only supported inside the same JVM. If you want<br />
IPC, you have to use sockets or xfer data using files. I would recommend the sockets<br />
approach, it has the added advantage of working not only between process, but<br />
across the network as well.<br />
Use of other IPC mechanisms, like shared memory, pipes, mail boxes, etc, are not<br />
supported by the JVM core. You could always roll your own native code, but why<br />
bother when you have access to sockets?<br />
RMI is another possibility but it all depends on what you want to do. I'll let the RMI<br />
experts talk about this option.<br />
And CORBA, if you want to get real fancy.<br />
