title: Get array with json object out of a string
body: <p>I have a java spring boot project that makes an REST API call and one element of the returned json is as follows:</p>
  <p><code>&quot;args&quot;: &quot;[[\&quot;element_1\&quot;],[\&quot;element_2\&quot;],[\&quot;{\\\&quot;payload\\\&quot;:\\\&quot;{\\\&quot;Header\\\&quot;: \\\&quot;Header_title\\\&quot;, \\\&quot;Content\\\&quot;: \\\&quot;Content of the payload\\\&quot;}\\\&quot;}\&quot;]]&quot;</code></p>
  <p>My objective is to get the JsonObject &quot;payload&quot;. I can get the string using
  <code>JsonObject argString = (JsonObject) jsonParser.parse(originalJsonObject.get(&quot;args&quot;).toString());</code>
  (using the package com.google.gson.JsonObject) but I can't get the two-dimensional array out of the string.</p>
