title: Extract specific data from json object and store them in a list
body: <p>I´m new to the world of json format. I have Json info stored in a json object and I only want to extract name key values in a list. At least I have one user and sometimes more than one user. Extraction using Java or Groovy.</p>

          &quot;emailAddress&quot;: &quot;example@example.com&quot;
        },
        &quot;role&quot;: &quot;REVIEWER&quot;
      },
      {
