Using JENA API - Getting all the classes from OWL file

Question

Is it possible to get name of all the classes present in OWL file using JENA and store in the Array List?

   OntModel base = ModelFactory.createOntologyModel(OntModelSpec.OWL_MEM, null);
    OntModel model = ModelFactory.createOntologyModel(OntModelSpec.OWL_MEM_MICRO_RULE_INF, null);

    String NS = "http://www.abc.com/abcportal/abc.owl" + "#";

base.read("file:abcInstance.owl");
    ExtendedIterator<OntClass> iter = base.listClasses();

    while ( iter.hasNext()){
        System.out.println(iter.next());
    }

Answer 1

Yes it is, see the Javadoc for OntModel.listClasses . You can easily copy the contents of the Iterator into an array or List . That you're asking the question suggests that you'll probably benefit from reading the Jena ontology API documentation
