"thinking in java" vs "On java 8"
i started reading 'thinking in java' based on java SE5, but then i found the author's newer book on google play 'on java 8'. i was just wondering have you read it, i think it is the updated replacement for java 8? in your opinion would i still be better off reading 'thinking java' instead of that
