What is applet

Answer 1

What Is an Applet?
An applet is a small application that supports and enhances the hosting web application. Commonly created using the Java programming language, applets run within a web browser. Applets can either be small enhancing programs or stand alone as complete applications in themselves, since they have access to the complete Java application program interface (API). Applets are usually embedded within the syntax of the hosting web page, which loads on request by the user. Hypertext Markup Language (HTML) code is received by the web browser and translated into dynamic, graphical, and informative pages we see displayed on our devices. Web pages that contain dynamic content such as animation and sound effects, making the user's experience more interesting, are the result of these small programs called applets.
