Hello Andy,
Thank you very much for your help
the problem is resolved and now I don't have any error but when I run my
class I got several errors concerning jena as:

and I don't have any result of my query. my query is like this:
InputStream in = FileManager.get().open("D:/universityexample.owl");
if (in == null) {
throw new IllegalArgumentException( "File: " +
"D:/universityexample.owl" + " not found");
}
OntModel model =
ModelFactory.createOntologyModel(OntModelSpec.OWL_DL_MEM_RDFS_INF);
model.read(in , "","RDF/XML");
try{
if (keyword.contains("Students and their school"))
{
String sparqlQuery =
"PREFIX personne:<
http://www.semanticweb.org/hp/ontologies/2016/6/untitled-ontology-87#>\n" +
"PREFIX rdf:<http://www.w3.org/1999/02/22-rdf-syntax-ns#>\n"
+

"PREFIX swrlb:<http://www.w3.org/2003/11/swrlb#>\n" +
"SELECT ?Students " +
"WHERE {\n" +
"?Students rdf:type personne:students.\n" +
"} ";
Query query = QueryFactory.create(sparqlQuery) ;
Dataset dataset=DatasetFactory.create(model);
QueryExecution qexec =
QueryExecutionFactory.create(query,dataset) ;
ResultSet resultset = qexec.execSelect() ;
Thank you for your help :)
