Java Reflections API (example)

Looping through Objects in a list, checking whether each Object contains a method called getId(). If so, invoke the method and show the result:

if (result instanceof List) {

  for (Object o : (List) result) {
    Method[] mArr = o.getClass().getMethods();
    
    for (Method m : mArr) {
      if ("getId".equals(m.getName())) {
        Object obj = m.invoke(o);
        LOG.info("Value of getId() " + obj.toString());
      }
    }

  }
}
