Java异常Stacktrace

Question

I'm creating application and in this application I need to write all exceptions to file. I need to get line number of error and I'm using this to get line number:

entry.setStackTrace(e.getStackTrace()[0].getLineNumber());

But I'm afraid, that stacktrace can be null. So my Question is - can stack trace be null?

Answer 1

If an Exception has been thrown, the

e.getStackTrace()

can't be null.

But why you don't use the std Java Logger or the android logger for Logging outputs?
