Innovative Teaching Practice of Java Programming Courses Based on Knowledge Graph and Competition Practice Under the Background of New Finance and Economics

The Java programming course is a fundamental course for computer related majors and the cornerstone of the computer related curriculum system. Its characteristics are strong practicality and a wide range of knowledge points. The goal of the new financial and economic education reform is to cultivate high-quality composite talents guided by social needs. With the development of artificial intelligence technology, how to better serve teaching and learning with the help of artificial intelligence technology and cultivate high-level talents is a challenge faced by programming courses. This paper mainly studies the use of multiple artificial intelligence learning platforms and competition driven approaches in teaching activities, utilizing various digital technologies such as knowledge graphs, Artificial Intelligence teaching assistants, and online assessments, to achieve a closed- loop teaching process of "teaching assistant testing evaluation teaching", promote the mutual growth of teaching and learning, and enhance students' comprehensive practical abilities. The research and practice in this article can provide ideas and references for cultivating high-quality new financial talents in programming courses for college students.
