About
de·caff provides Java programs, some with source code included, and a small blog about advanced Java topics.
Why de·caff?
Java's package naming convention states that every Java programmer should place her classes in a package starting with the reverse of her email's address internet domain thus avoiding name clashes. So every package by anyone from caff.de has to start with de.caff which matches the attitude of your host who never drinks coffee.
