### Question:
QuestionPaperGenerator { public static Map<String, Object> fetchChildDetails(Node node) { return node.getOutRelations().stream() .filter(relation -> StringUtils.equalsIgnoreCase(ASSESSMENT_OBJECT_TYPE, relation.getEndNodeObjectType())) .collect(Collectors.toMap(Relation::getEndNodeId, entry -> entry.getMetadata().get(INDEX))); }  static File generateQuestionPaper(Node node); static Map<String, Object> fetchChildDetails(Node node); static Map<String, Object> getAssessmentDataMap(Map<String, Object> childData); static String getFileName(String prefix);  }### Answer:
