Print Stacktrace into Textarea in JavaFX

问题

I would like to print the stacktrace of a throwable into a Textarea

Something like this:

textArea.setText(throwableElement.toString() + "\n" + throwableElement.printStackTrace());

Is that possible?

I hope you can help me

Thanks

You can do

StringWriter stackTraceWriter = new StringWriter();
throwableElement.printStackTrace(new PrintWriter(stackTraceWriter));
textArea.setText(throwableElement.toString() + "\n" + stackTraceWriter.toString());
