Can java objects access their instance methods when coding in groovy?

I have written two java classes, with a constructor and an instance method to return an JSON array. I want to access instance of these classes in groovy and call the getArray method on these objects I have instantiated. My problem is I do not know how to access those getArray methods?? Here is some code:

import JSONEncounterDesk;
import JSONHelpDesk;
import org.codehaus.groovy.grails.web.json.JSONObject

    class UsersController {

        def index() { 
            JSONEncounterDesk currEncounterDesk = new JSONEncounterDesk();
            JSONHelpDesk currHelpDesk = new JSONHelpDesk();

            return render(contentType: 'text/json') {
                ret
            }
        }
    }
