Steps involved to perform this operations are following:
For Joomla 3 & less:
jimport( 'joomla.user.helper' );
$user = JFactory::getUser();
$userId = $user->id;
$userProfile = JUserHelper::getProfile( $userId );
echo "Main Address :" . $userProfile->profile['address1'];
For Joomla 4+:
use Joomla\CMS\User\UserHelper;
$userProfile = UserHelper::getProfile();
Hope this helped.
