To assist novice students in their self-studies of Java programming, we have developed the Java programming learning assistant system (JPLAS) where the answer interface was implemented on a web browser using HTML/CSS/JavaScript. In Java programming, some concepts, such as generics, lambda expressions, and streams, can be very difficult for novices, although they are useful and essential in implementing practical programs. Therefore, proper exercise problems with an assisting function to help their understanding should be implemented in JPLAS. In this paper, we present the grammar-concept understanding problem (GUP) for these concepts in JPLAS and implement a commentary function in the answer interface. GUP is designed for learning fundamental concepts by asking key elements appearing in a source code. The commentary function provides hints at three steps: 1) the output of the code, 2) the code summary made by ChatGPT, and 3) the first character of each correct answer. Besides, for the give-up student, it can show the correct answer itself with its explanation made by ChatGPT. For evaluations, we generated 10 GUP instances with the commentary function and assigned them to junior students taking the Java programming course in Okayama University, Japan. The results validate the efficacy of the proposal in improving understanding levels of challenging topics. We employed three generative AI models, namely ChatGPT, Tencent Hunyuan, and Google Gemini, to generate hints through the commentary function. A comparison of the generated hints showed that ChatGPT produced the most effective results. Consequently, we adopted ChatGPT to generate 10 GUP instances, which were then assigned to junior students enrolled in the Java programming course at Okayama University, Japan.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告コンピュータと教育（CE）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2026-03-07","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"2026-CE-184"}]},"relation_version_is_last":true,"weko_creator_id":"80578"},"updated":"2026-03-02T06:59:16.348912+00:00","created":"2026-03-02T06:59:12.138107+00:00","links":{}}
