With the rapid development of computer technology, various programming languages continue to improve and innovate, and the scopes of their daily applications are also expanding. Java occupies a unique corner in computer software development due to its orientation, independence, directness, and other advantages, and it is a programming language necessary for many computer applications. This paper further analyzes the programming advantages that Java occupies in software development through a brief introduction to the basic definition and characteristics of the Java programming language. Besides, through the mainstream application of the main technology of Java programming, this paper further analyzes and summarizes the Java programming language. We hope that the research on Java programming characteristics and technical analysis can provide references for related parties.
