如何在Java中检查SPARQL查询是查询还是更新？

import org.apache.jena.query.Query;
import org.apache.jena.query.QueryFactory;

public class SparqlQueryTypeChecker {
    public static void main(String[] args) {
        String sparqlQuery = "SELECT ?subject ?predicate ?object WHERE { ?subject ?predicate ?object }";
        
        Query query = QueryFactory.create(sparqlQuery);
        
        if (query.isAskType()) {
            System.out.println("This is an ASK query.");
        } else {
            if (query.isConstructType()) {
                System.out.println("This is a CONSTRUCT query.");
            } else if (query.isDescribeType()) {
                System.out.println("This is a DESCRIBE query.");
            } else if (query.isSelectType()) {
                System.out.println("This is a SELECT query.");
            }
            
            // Additional code to handle SELECT, CONSTRUCT, and DESCRIBE queries
        }
    }
}
