A way to let a thread live after the application has died ?
Hi,
Is there a way to let a thread live after the application that created the thread has died ?
I could not managed to do so using the code below:
// MyThread.java
import java.io.*;
publicclass MyThreadextends Thread
{
public MyThread(){}
publicvoid run()
{
try{
RandomAccessFile rf =
new RandomAccessFile("file.txt","rw");
for(int i = 0; i < 50000; i++)
rf.writeChars(i +" ");
rf.close();
}
catch (Exception e){
System.out.println(e.getMessage());
}
}
}
// RunThread.java
publicclass RunThread
{
public RunThread(){}
publicstaticvoid main(String[] args)throws Exception
{
new MyThread().start();
System.out.println("RunThread is over! (MyThread should continue)");
}
}
Thanks a lot.

Aaargs. Sudden Impulse. sorry for the earlier post.It should NOT be a daemon.
Anyways ,on my system ( without any modifications) the code works perfectly.
Anyways you could do something like
Thread t = new MyThread();
t.start();
t.join(); // Wait for it to die.
Hi nishuteddy,
Thank you for taking your time.
I noticed that my problem is not releated to threads actually.
What I want is to start a program from the consol(command prompt) and let the system to get inputs from its prompt while the application runs. It's like "nohup" in UNIX: start it and continue.
In my situation, after I started the application in consol, the system doesn't allow me to do another thing while waiting for the application to stop.
I think, if I could manage to do so, then I can start the application within my Java application by creating a Runtime process and executing it.
Am I wrong?
Many thanks.
Well, technically it's impossible!
After all, a thread belongs to a process. If a process dies, all its threads must have died too. If a thread of excecution continues after the process information has been removed from the operating system, then that is a serious bug in the operating system!!
But maybe you mean something else?
You could have a windowing application which didn't kill itself when the main window was closed.
