Key concepts

Java applet

Java applets are small programs written in the Java programming language that were traditionally used to add interactive features to web pages. These applets could perform various tasks, such as creating animations, playing sounds, or handling form data. A distinctive feature of Java applets was their ability to run directly in a web browser, leveraging the power of the Java Virtual Machine (JVM) to execute the code.
Java applets were embedded in HTML documents using a special tag, which specified the class filename of the applet and any parameters required to run it. However, applets have fallen out of favor due to compatibility issues and security concerns, as modern browsers have ceased support for them. Instead, technologies such as JavaScript and HTML5 have become the standard for providing interactivity on the web.

JSP scriptlet

Within the realm of web development, JSP (JavaServer Pages) scriptlets have been a useful tool for embedding Java code directly into web pages. A JSP scriptlet is enclosed within <% and %> tags and allows developers to generate dynamic content to be displayed on the webpage.
JSP scriptlets are part of a larger Java-based technology stack and are used in web applications hosted on servers. The server processes the Java code within the JSP scriptlet before delivering the final HTML to the client's browser. This means that the Java code is not exposed to the end user, maintaining security and cleanliness of client-side code.
Commonly seen in enterprise environments, JSP scriptlets offer a way to weave business logic into the presentation layer of web applications. However, evolving best practices recommend separating logic from presentation by using JavaBeans or custom tags, thus improving maintainability.

XML

XML, which stands for eXtensible Markup Language, is a versatile and widely-used format for representing structured data in a text format readable by both humans and machines. Unlike HTML, which is focused on how data is displayed, XML emphasizes the data's structure and organization, making it ideal for data interchange between systems.
XML provides a set of rules for creating custom markup languages. Each piece of data is enclosed within tags, which are user-defined to match the structure of the data being represented. This allows developers to create an understandable and extensible data format that can be customized to meet specific application needs.
Some advantages of XML include its platform independence, ability to transport data over different systems, and support for complex data structures. It's often used in web services, configuration files, and data exchanges in enterprise environments. Despite its verbosity, XML remains a fundamental technology in designing interoperable systems and applications.
