Ask HN: I'm gonna have to go ahead and ask you to learn Java.

Any recommendations on books or resources to get up to speed with Java quickly. I'm a pretty experienced programmer looking to port some iOS applications to Android and get to know Java so I know when to dip into the Java platform from Clojure.

Also, where can the java community be found online? Thanks in advance.

Any recommendations on books or resources to get up to speed with Java quickly

My knowledge of Java books is probably pretty out of date, but I got some mileage out of the Deitel & Deitel book Java: How To Program.

Also, where can the java community be found online?

http://www.jroller.com

http://www.theserverside.com

http://saloon.javaranch.com

all come to mind...

Reg. community, the list cannot be complete without the SO tag - http://stackoverflow.com/questions/tagged/java

Cool. What about java related IRC channels?

On Freenode:

##java

#spring

#eclipse

#jboss

#hibernate

#lucene

are ones I sometimes lurk in, that are fairly active. The Triangle (NC) Java User's Group also have a channel, but it's not terribly active most of the time.

#trijug (again, on Freenode)

Also, if you're not already in #startups, it's a channel full of HN users... might be of interest to ya.

Sweet! Thanks for the great list.

I would like to put in a plug for EFNet #java - idle there long enough and you may learn some things.

Disclaimer: I am an op there.

The official Java tutorial is also worth taking a look at. It's free, updated and more concise compared to most books.
