How to create fields from a txt file for Lucene indexing?

[Eder]

Hi all

I'd like to create fields based in a txt.file, like the foollowing example:
File1.txt
Author: Eder
Description: Indexing txt files in Lucene Tutorial
Category: Software Development

File2.txt
Author: Cecilia
Title: Preventioning Fever
Category: Health y Wellness

So, I'd like to create the fields "Author", "Description", "Title" and 
"Category" by reading the files. If I got the texts, I would do something 
like:

Document doc = new Document( );
doc.add(New field("Author","Eder"));

But this info is in txt files, so how can I read the file and get the data?
