I am curious - why do you start a Thread that ends almost immediately?

And why have you not responded to my previous comments on this matter?

I am also curious - why have you continued to ignore several people's advice
not to ignore the Exception?

Please answer these three questions.

That depends on what you mean by fine. When I loaded your class into NB
and built it, I ran it and all I saw was a whole bunch of windows
appearing, like 1 second apart. Is that what you intended because to
me, it doesn't have a very good level of usability. I am running under
jdk1.6 on Ubuntu Feisty.

I think you may be confusing "troll" and "spammer". A troll can work on
a single newsgroup. See http://en.wikipedia.org/wiki/Internet_troll.

Personally, I don't care whether someone is a troll or not. If a repeat
poster shows no signs of making use of any advice, trying to help them
is a waste of time.

The idiom you show here doesn't do that. Does it help to use an idiom that
doesn't work because you can't think of one that does?

All this code does is start a Thread that immediately stops.

You might consider java.util.Timer or one of its ilk.

That's not true. I remember other posters telling you to at least log the
Exception.

For example, assuming log4j:

import org.apache.log4j.Logger;
public class SomethingOrOther
{
private Logger logger = Logger.getLogger( getClass() );
public static void main( String [] args )
{
try
{
doSomethingThatMightThrowAnException();
}
catch( AnException exc )
{
String msg = "AnException: "+ exc;
logger.error( msg ); // /* or use */ System.err.println( msg );
}
}
}

Clearly, your definition of troll differs from mine.

To me, a troll in this context is a person whose purpose is to disrupt
online discussion, rather than participate in it.

I don't know if you are a troll or not, but I can see how a reasonable
person might deduce that you are a troll based on your behaviour (e.g.
ignoring questions presented to you, asserting definitions that are not
generally agreed upon, etc.).

Putting the accusations aside for a moment, if you really want help
with your problems, I suggest you cooperate with the people trying to help
you. You might also want to work on your articulation skills. Based on
your writing, you sound like a native speaker of English, but I often have
trouble understanding what you're talking about. I saw elsewhere in this
thread you posted something which vaguely resembles answers to Lew's
questions. Note however that Lew specifically mentioned 3 questions, and
you posted 2 pseudo-answers. It's stuff like that that makes it hard to
understand what you're saying and thus hard to help you.

I made several mistakes in this example, at least one carelessly. It wasn't
meant to be compilable anyway, but I really shouldn't have mixed static and
instance stuff:

import org.apache.log4j.Logger;
public class SomethingOrOther
{
static class AnException extends Exception
{
public AnException(){}
public AnException( String msg ){ super( msg ); } // other two omitted
}
private final Logger logger = Logger.getLogger( getClass() );
private void doSomething() throws AnException
{
throw new AnException("oops");
}
public final void handle()
{
try
{
doSomething();
System.out.println( "Success" );
}
catch( AnException exc )
{
String msg = "AnException: "+ exc;
logger.error( msg ); // /* or use */ System.err.println( msg );
}
}
public static void main( String [] args )
{
SomethingOrOther soo = new SomethingOrOther();
soo.handle();
}
}

.... non comprende, monsiuer. wouldn't it be easier to just put a
System.out.writeln("oops") after i have caught it since it theoretically
will never get there. we catch for show.

You do /not/ catch Exceptions just for show! This is what people have been
telling you.

You catch Exceptions to allow issues to be detected and resolved, and to
permit the program to resume a valid state. It is /not/ just for show!

You do /not/ catch Exceptions just for show!

I don't know what you mean by "after" you've caught the Exception. The code
sample above shows where you would put the System.err.println() (a better
choice for error messages than System.out). I have eliminated the log4j stuff
to simplify matters.

It is not enough to simply create an error message without the Exception
information. You should include information from the Exception in the message
so you can solve what happened. I don't show it in the example above, but it
is usually helpful to log at least part of the stack trace.

This code example is complete. Did you try running it? What happened?

That's two questions I'm asking. Make sure the answer to the first one is
"yes" before replying.

When I run it this happens:

$ java testit/SomethingOrOther
AnException: testit.SomethingOrOther$AnException: oops

I ran the exact code I sent, save that it was in a package.

This is not what you saw?
