Hardcore Java

Hard Core Java is an advanced book that focuses on the little-touched but critical parts of the Java programming language that expert programmers use. We're not talking about trivial things; we're talking about difficult but extremely powerful and useful programming techniques like reflection, advanced data modeling, advanced GUI design, and advanced aspects of JDO, EJB and XML-based web clients. This unique book reveals the true wizardry behind the complex and often-mysterious Java environment.

Robert Simmons, Jr. started programming when floppy disks were really floppy and 64 kilobytes of RAM was considered state of the art. From his early days of programming BASIC and Logo on an Apple IIe, he advanced through Pascal and C to arrive in the object oriented realm of C++. When Java first came out, he knew that the infant language would become a serious player amongst corporations; Robert learned Java and began using it as his primary language for programming in 1997. Although Robert is American, he lives and works as a Senior Software Architect in Germany.
