How to modify a tuple record (MDM Java API)

Hi Experts,

Kindly advice how to do retrieve the tuple ID of the below.

We have a main table and one of its Tuple is Address. on this tuple we have one of the field is Address type.

Now the requirement is, we have just two know fields Person ID (from Main table) and Address type from  that tuple. And based on this two values we need to do a search and update the address of that particular person ID record.

Please advice the best approach for performing this.
