使用JENA API-从OWL文件中获取所有类

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
