How to display the stacktrace?

[Aaron Fude]

Hi,

Very often, for debugging purposes in Swing applications, I like to
see the stacktrace so I do the following:

try {
throw new RuntimeException();
}
catch (Exception e) {
e.printStackTrace();
}

Is there a more tasteful way of accomplishing this?

Thanks!

I think just this will work:

Exception e = new Exception();
e.printStackTrace();

or even

new Excpetion().printStackTrace();

No need to throw it first.

Cool beans!

How about Thread.dumpStack()?

Or if you want control over where it goes, then you can get
an array from Thread.currentThread().getStackTrace() and
print each element of that, or make it available in your GUI
somewhere if that's appropriate/convenient.

You can also do it manually with StackTraceElement :

catch(Exception e)
{
StackTraceElement[] s=e.getStackTrace();
int n;
for (n=0; n<s.length; n++)
{
g.drawString(s[n].toString(), 0, n*20);
}
}

What is distasteful about your existing code. If you want some
