title: get elements from json
body: <p>I want to have a java list for all elements which are in the "in" or "out" element.</p>
  
  <p>My json string:</p>
  
  <pre><code>{"in":[
         {"id":4,"ip":"192.168.0.20","pinSysNo":4,"pinSysName":"pg6","folderName":"gpio4_pg6","alias":"d","direction":"digital_in"},
         {"id":3,"ip":"192.168.0.20","pinSysNo":3,"pinSysName":"pb18","folderName":"gpio3_pb18","alias":"c","direction":"digital_out"}
        ],
   "out":[
         {"id":1,"ip":"192.168.0.20","pinSysNo":1,"pinSysName":"pg3","folderName":"gpio1_pg3","alias":"a","direction":"digital_in"},
         {"id":2,"ip":"192.168.0.20","pinSysNo":2,"pinSysName":"pb16","folderName":"gpio2_pb16","alias":"b","direction":"digital_in"}
              ]
  }:""
  </code></pre>
  
  <p>Until now I did this way:</p>
  
  <pre><code>String message = json.findPath("in").textValue();
  </code></pre>
  
  <p>But this way can only access to the first hierarchy.</p>
  
  <p>My json example show two elements in the "in" element. How I can get a list of these internal "in" elements?</p>
