+#### Render JSON RTE Contents
+To get multiple entries, you need to provide the stack API key, environment name, delivery token, content type and entry UID. Then, use the Contentstack.Utils.jsonToHTML function as shown below:
+
+```java
+
+import Contentstack
+Stack stack = Contentstack.stack("apiKey", "deliveryToken", "environment_name");
+Query query = stack.contentType("content_type_uid").query();
+query.includeEmbeddedItems(); // include embedded items

+        if (error == null) {

+            String[] keyPath = {
+            "rte_fieldUid", "group.rteFieldUID"
+            };
