title: Convert objects in ArrayList to String
body: <p>I'm trying to return a concatenated string from objects which have been placed in an ArrayList.</p>
  
  <pre><code>public String displayProperties() {
      StringBuilder propertyList = new StringBuilder();
      properties.forEach(propertyList::append);
      String e = propertyList.toString();
      return e;
  }
  </code></pre>
  
  <p>When I return e. I get an object reference.</p>

  </code></pre>
