Ask HN: Good Java books for aspiring Clojurians?
I feel I would be much more effective in Clojure (and consequently, the Java ecosystem) if I spent some time with Java, or were at least more familiar with it.  With the wealth of Java books, it is a bit intimidating to choose one...<p>So HN: What would be a good Java book for a Clojurian with a solid OO background, but no Java experience?
