I want to write a SPARQL query to count how many times the foaf:account property is used and how to execute it in Java.

Can someone help me please?

In this case, i want the SPARQL query to return "2".

This forum is dedicated to technical queries on Refinitiv product APIs. From the query, I think it is not Refinitiv APIs.

However, I found the same question posted on stack overflow.
