New Echo Nest Java client released

We’ve just released version 1.1 of the Echo Nest Java Client.  The Java Client makes it easy to access the Echo Nest APIs from a Java program.  This release fixes some bugs and improves caching support.   Here’s a snippet of Java code that shows how you can use the API to find similar artists for the band ‘Weezer':

 ArtistAPI artistAPI = new ArtistAPI(MY_ECHO_NEST_API_KEY);
 List<Artist> artists = artistAPI.searchArtist("Weezer, false);
 if (artists.size() > 0) {
     for (Artist artist : artists) {
          List<Scored<Artist>> similars =
                artistAPI.getSimilarArtists(artist, 0, 10);
          for (Scored<Artist> simArtist : similars) {
               System.out.println("   " + simArtist.getItem());
          }
      }
  }

Also included in the release is a command line shell that lets you interact with the Echo Nest API.   You can start it up from the command line like so:

    java  -DDECHO_NEST_API_KEY=YOUR_API_KEY -jar EchoNestAPI.jar

If you are interested in playing around with the Echo Nest API but don’t want to code up your own application, typing in webservice URLs by hand gets pretty old, pretty quickly. The Echo Nest shell gives you a simpler way to try things out.
