Design Project Summary:

Through the recent mastery and learning of Java object-oriented programming, front-end knowledge and Java framework, as well as the development of this period of education and teaching system, I have learned more about the importance of Java learning. In the development of this system, I not only carried out many tests, but also tested the function of the system. In the implementation process of the paper, I put a lot of efforts into the realization of Java proficiency, and then I felt very happy to apply related technologies. In the process, I discovered that Java has an enormous amount of functionality to explore. Java is encapsulation, abstraction, polymorphism, and inheritance. The code can be reused and expanded to greatly improve the overall speed and efficiency of software development. As a student of educational technology, learning Java language well is of great significance to my future employment or the expansion of my knowledge. The main purpose of my study of programming is to improve my key skills and techniques in programming solutions to practical problems. Java object-oriented programming is a practical relatively very strong language, SpringMVC framework MVC three-tier architecture pattern, and the framework encountered in the design pattern of data access and logic operations are concentrated in the components to enhance the system’s reuse and expansibility. The expansibility of the system is greatly enhanced. As well as front-end jQuery, JS, JSP, CSS style master let me to the layout of the web page, style adjustment, font and so on to achieve more accurate web effect.
