hi,
i still have some more questions about threads and the differences between
linux-windows95.
In my application I got a similar behaviour between linuxwin95 if I set the
Priority = 1 on linux. On win95 it is 5. Is the behaviour of these values
somewhere defiened or does it depende on the virtual machine. If it depends
on the virtual machine how can I write programms which behave same or
similar on both platforms ?
One solution might be that all threads must communicate during there
execution about the methode interrupt(). But I think that this is often very
inconvinient and (in my case) very difficult to implemente. So in my case it
would be the best if the behaviour of a thread is well defiened.
And still another question:
When should I use native threads, when green threads ? Is there
anywhere a paper about pro/contra of this both kind of threads ?
Thanks for discussing this questions
Holger

Betreff: java and multithreading
Hi, I am new at this mailinglist so I am not sure if the following question
is still discussed.
I am a little bit astonished about the java multithreating under linux. For
me it looks like that the multithreading with the semantic java is much
better.
For example I tried the following programm:
class TestThread extends Thread {
String txt;
public TestThread(String t){
txt = new String(t);
}
public void run(){
for( int i = 0; i < 100; i++){
System.out.println( txt);
}
}
}
class main{
public static void main(String[] args ){
TestThread one, two, three;
one = new TestThread(" one ");
two = new TestThread(" two ");
three = new TestThread(" three ");
one.start();
two.start();
three.start();
}
}
I expected following output:
one
two
three
one
two
three
...
or similar. Under win95 everything went fine.
Unter suse-linux 6.1 with jdk1.1.7 and TYA JIT I got following output:
one
one
one
.
.
.
two
two
two
.
.
.
three
three
three
.
.
.
This did not look like multithreading. It is the same if I use native
threads and not green threads.
Has anybody an idea how to write a real multithread programm under
linux. I have to know it because we wrote a server and we want to run it
under linux and not under windows.
Thanks for our help
Holger
