Hi Kathy and Bert, I hope you get to read this, because it's been ages since I read one of your first Head First Java, and from that moment on I was hooked on Java, I believe it has been 15 years I believe and your book helped my achieve many things in my career starting from my very first java certification.
Back then there were not so many books, online courses, youtube videos etc, but I'm glad that pearls like Head First Java is still around because the quality can not be compared, there is no other source that teaches you Java like your book.
So for all this, THANK YOU! THANK YOU VERY MUCH!
And my question is a big one, if you are a Java 1.5 certified, that has worked a lot with Java 8, where do you start to catch up with the latest versions? does your book cover it all? and last but not least... Do you guys have a favorite new feature? pleaase explain
