Hey there Yehonathan, I've also just joined and was looking for a proper introduction tread (we really should have a pinned one).
I'm currently treading (ops) the path to a career change ;D
I found my way to the Ranch at Kathy's Head First
Java. Started a week ago, I'm about reaching half of the volume now.
Already planning the next reading. Is there anything better than Bruce's Thinking in Java 4th ed. by now?
