Object-oriented knowledge

You need to master: what is an object, what is a class; what is encapsulation, what is polymorphism, what is inheritance; what is an abstract class, what is an interface. After understanding the concepts, you also need to know how these concepts are embodied, such as what is the difference between classes and objects? How are classes encapsulated?

It is best to know several built-in objects of JSP, such as Session, Request, Response, and commonly used JSP tags, such as include, userBean, etc. It would be better if you become more familiar with JS and CSS, which will make the pages you create more user-friendly.

WebServer

A framework will be used to build your own application system. Frameworks will have a lot of reusable code, good hierarchical relationships and business control logic. Framework-based development allows you to save a lot of development costs. Currently popular frameworks include Struts and Spring.
