I have a background in C but found the java coding in the book quite straightforward. Best to use an IDE an avoid my mistake of trying to extend the pom.xml. Also be aware that you will need to track down some dependencies for the repository that's cited in the book - jar's for classifier4j are not included, so don't expect to clone in and have everything build straight away. I'm pretty sure the author stuffed up the first example in the book around Users Purchase History. Confusingly he sort of disregards "Did purchase" in his entropy calculation example and uses "has account credit" to split an entropy calculation for "read reviews".
