title: Parsing JSON Object using GSON and updating the JSON file (Search and Update)
body: <p>Below is my JSON Object</p>
  
  <pre><code>{
      "Germany": {
          "Languages": [
              "German",
              "English",
              "Austrian German"
          ],
          "Continent": "unknown",
          "Capital": "Berlin"
      },
      "China": {
          "Language": [
              "Standard Mandarin",
              "Cantenese",
              "English"
          ],
          "Continent": "Asia",
          "Capital": "Shanghai"
      }
  }
  </code></pre>
  
  <p>What I am trying to achieve is to search for a keyword [Eg: Germany] if it exists, then update the attribute <code>Continent</code> from <code>unknown</code> to <code>Europe</code>. </p>
  
  <p>How would we achieve this using GSON?</p>
