Q:

how to extract author details from pdf using java

I have 1000s and 1000s of PDF articles from which I need to extract only author name and his relevant details like address and email ID and whatever provided inside the PDF (I mean the content inside). I don't want to do this by getting the details associated with the metadata of the PDF. Since I tried that where I end up with only less details like author name, title and some other usual details which I do not need at all. 
I have gone via all APIs in internet, but still I did get the solution. I need to do it in Java.

A:

I think you can't get it directly from any library.
Use iTest library for reading pdf. Once you are able to read text find the Author using regular expression.
