Get stacktrace of function with throws Exception

Question

Lets say I have a function like this

public JSONObject parseMessage(InputStream fileName) throws Exception {

And it throws an error where can I get the stack trace of that?

I know if I have something like

try {} catch(Exception e) {//I could save it to a var here}

But how to I save the stacktrace to are variable with a function that throws Exception?

Thanks for all the help

You want to get the stacktrace in a function before you throw an exception from that function? — Jonny Henly, Oct 28 '16 at 22:12
You could `catch` it, work on it, and then `throw` it again. — LinuxDisciple, Oct 28 '16 at 22:13

You can use Apache commons to convert an Exception stack trace to String.

This class is available in Apache commons-lang-2.2.jar:

org.apache.commons.lang.exception.ExceptionUtils.getStackTrace(Throwable)

Or just use the existing `.getStackTrace()` which returns `StackTraceElement[]` which has a perfectly good `.toString()`. – LinuxDisciple Oct 28 '16 at 22:15
Or `Arrays.toString(Thread.currentThread().getStackTrace());`. – Jonny Henly Oct 28 '16 at 22:16
