With the development of computer technology, the traditional computer language application training model is no longer suitable for the needs of society. In view of the current research status of curriculum group construction, the application-oriented Java curriculum group research ideas are proposed, and combined with the actual situation of the school, the main content and implementation plan of the application of Java curriculum group construction are given. Therefore, the establishment of an application-oriented Java curriculum group model has become a modern. The inevitable trend of the development of the computer age has become an important element of learning computer languages. Through tangential research on the application of Java language programming in Java courses, it is possible to merge content-based and internally related Java courses, and eliminate obstacles between courses and enhance professional capabilities. The research goal of this article is to better show the learning content, ability goals, technical challenges and implementation process in the Java course group. The purpose of this article is to learn and apply the research and design of the Java course group, to design target algorithms, reform independent practice, create experimental model support, and build a Java course group platform for scientific and technological innovation practice, so as to do the traditional computer language application training model. Innovatively developed a new application java course group model. This article starts from the relevant knowledge and theory of practice, takes the application-oriented Java course in the current computer age as the perspective, and promotes the application-oriented Java course group experiment for specific goals. In the experiment process, summarize the knowledge value, ability goals and technical goals of the implemented java course group, and implement rigorous experiments through theoretical and practical training courses to innovate and develop traditional computer language teaching application models. Experimental evidence shows that the application-oriented Java course group is a combination of student-oriented and application-oriented programming language courses, verifying a more student-friendly application-oriented teaching method, and constructing a new model of application-oriented Java course group.
