Here is the code, I have typed it so might have some mistakes.
OntModel model=ModelFactory.createOntologyModel();
InputStream in =FileManager.get().open("D://ont/soccer.owl");
if (in==null) {
throw new IllegalArgumentException( "File: " + " not
there");
} model.read(in,"");
String ns="
http://www.semanticweb.org/neha/ontologies/2016/6/untitled-ontology-11#";;
OntClass team = model.getOntClass(ns + "Team");
OntProperty goals=model.getOntProperty(ns+ "Goals");
OntProperty wins=model.getOntProperty(ns+ "Wins");
//Goals and Wins are entered by admin, so I want to sum the newly entered
//goals with previous stored in ontology.
//This is why I need integer values from these properties.
SELECT *" +
" WHERE { ?x rdf:type ont:Team . ?x ont:Goals ?goal . ?x
ont:Wins ?wins} filter(?goal>10 && ?wins<?goal ) ";
//the query also gives error , not recognizing Filter.
Query query = QueryFactory.create(queryString) ;
QueryExecution qexec = QueryExecutionFactory.create(query,
model);
ResultSet results = qexec.execSelect() ;
while(results.hasNext()){
QuerySolution soln = results.nextSolution() ;
int lit = soln.getLiteral("goal").getInt() ;
int lit2=soln.getLiteral("wins").getInt() ;
System.out.println("goals"+lit);
