Are you interested in data mining? Yes… you are reading this blog. Do you use to program in Java? If yes, then the book Java Data Mining can interest you. It is briefly described by KDnuggets. To my point of view, Java is perhaps not the best language to use for data mining. Either you are in the industry and need a fast running application; then you will certainly use C++ or .NET. Or you are doing research and you need more interactivity and simplicity while coding; then you will probably use MATLAB for example. Java is neither as fast as C++, nor as easy to use as MATLAB. Perhaps this book will tell you why to use Java for data mining. By the way, a good book on data mining (with Java examples) is Data Mining: Practical Machine Learning Tools and Techniques.
