 This book is very systematic and well-organized. It definitely is a good choice for Java beginner to start. Suggested solutions to part of exercises are provided by the author, but only the registered instructors have access to them from Pearson website. I'm trying to finish all the exercises in this book (very slowly 🐢). If you come across any difficulties in completing these exercises, I will be very happy if my solution can provide some insights more or less. If I haven't solved the exercise you are facing, please do let me know, I'll update the solution preferentially. Moreover, contributions of any kind to this project are welcome!
