Leaning heavily on my Google-fu skills and a copy of Bruce Eckel's Thinking In Java, I have learned things about how member variables are initialized in Java (to zero, for the most part), about why I should use ArrayList instead of Vector, about StringBuilder, Java iterators, and all manner of things that start to make a lot more sense when you actually use them to write code.
This is not tremendous progress, but it is a start.
And you can't finish if you don't start.
