What is the difference between Java and JSP

The differences between Java and JSP are: 1. Java is an object-oriented programming language, while JSP is a web page technology based on Java for developing dynamic content; 2. Java is responsible for logical business processing, and JSP is responsible for page display and so on.

【Recommended course: Java Tutorial】

JAVA is a programming language that can write applications and is mainly used in network programming. JSP is a network programming language based on JAVA and can only be used on web pages. Next, I will introduce the differences between Java and JSP in detail in the article, which has a certain reference effect and I hope it will be helpful to everyone.

Java Language

Java was originally developed by Sun Microsystems, initiated by James Gosling and released in 1995 as the Sun Microsystems Java Platform (Java 1.0 [J2SE ]) core components. As Java has grown and its widespread popularity, multiple configurations have been built to suit various types of platforms. For example: J2EE for Enterprise Applications, J2ME for Mobile Applications. The Java language has the following characteristics: object-oriented, platform independent, portability, multi-threading, high performance, distributed, etc.

JSP Language

JSP stands for JavaServer Pages, which is a technology used to develop Web pages that support dynamic content. It helps developers to insert Java code in HTML pages by using special JSP tags, most of which start with <% and end with %>.

The JavaServer Pages component is a Java servlet designed to implement the user interface role of a Java Web application. Web developers write JSPs as text files that combine HTML or XHTML code, XML elements, and embedded JSP actions and commands. Using JSP, you can collect user input through web forms, display records from a database or other sources, and dynamically create web pages.

JSP tags can be used for various purposes, such as retrieving information from a database or registering user preferences, accessing JavaBeans components, passing control between pages, and sharing information between requests, pages, etc.

The difference between Java and JSP

(1) Java is a general computer programming language that is concurrent , class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. And JSP is a technology that helps software developers create dynamically generated web pages based on HTML, XML, or other document types.

(2) Java applets are written using the Java programming language. JSP uses a mixture of "scriptlet elements" (Java code) and "markup" (usually HTML or XML) programmed to deliver data-driven ("dynamic") web pages.

(3) Java is an object-oriented language, and JSP can be understood as a script

(4) Java is mainly responsible for logic and business processing, while JSP is mainly responsible for page presentation

(5) The essence of JSP is servlet, and the essence of servlet is Java class
