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?
I have already tried setting a timer but the data is always lost receiving.
Without more details, it is hard to give a complete answer. Nevertheless, here is the code for starting two threads:
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 simultaneously unless 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.
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?
I think you might have missed something significant with either Threads, Streams or both :-)
You can start a new thread like this:
myThread.start();
The thread will be started and the run() method will be executed automatically by the jvm.
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.
