That depends on a lot of things. An XML file i very easily read by
humans and portable but often not very scalable. A database is very fast
and scalable. A binary file can be easy to work with (or very very hard).
What would be the typical usage ? And how many records would the file hold ?
There are gazillion ways to emit data. The simplest is to open a file for writing, say in a variable 'wr' -
import java.io.PrintWriter;
...
PrintWriter wr = new PrintWriter( someFileName );
...
wr.println( foo.getProperty().toString() );
Of course, 'toString()' in most cases will not give you what you want, but it's a start.
Really you should just read the Javadocs on the java.io package, and the tutorial:
