Hi Budi Kurniawan ..... Welcome to Javaranch I have heard a lot about this book and I have read its reviews on amazon.com. It seems to be a nice book, going by the reviews posted on amazon.com. Do we have an e-book of this edition ???. If yes then from where can I download it. Unfortunately I am not able to purchase a hardcopy of this book due to non-availability in our city.
