Beside the examples that come with BitcoinJ and the documentation on Google Code, does anyone know of any tutorials for using BitcoinJ?
There was a 3 part article in JavaWorld about bitcoinj in 2011. It is obviously a bit dated but is a thorough introduction to it. First part: http://javaworld.com/javaworld/jw-11-2011/111122-bitcoin-for-beginners-part-1.html
I have found the snippets in here helpful: Bitcoinj API.
