JAVA: How to capture java exception stack trace in String

Many a times you might need to capture java exception (stack trace) in string, here is a small code snippet to do that:

StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw, true);
throwable.printStackTrace(pw);
String stackTrace = sw.getBuffer().toString();

This same method can be used to capture string from other streams and assign it to a String/StringBuffer.
