## Update Group

*In other words, as a group owner, how can I update the group details?*

You can update the existing details of the group using the `updateGroup()` method.

    Group group = new Group(GUID, groupName, groupType, password);

      @Override
      public void onSuccess(Group group) {
        Log.d(TAG, "Groups details updated successfully: " + group.toString());
      }
      
      @Override
      public void onError(CometChatException e) {
