I have just finished reading a neat little book about functional programming for Java developers by Dean Wampler. The book is only sixty pages long so it’s a really fast reading. This is a book for Java programmers and others working in the object oriented paradigm that haven’t read about or done any functional programming before. If that fits you then this book may be a good choice to read. Otherwise, I recommend that you seek more advanced and in-depth books in the subject instead. But this text will not be a review of the book. I will instead comment on the use of the functional structure and its paradigm in languages like Java that is not designed for it.
