The
<applet>tag in HTML was used to embed Java applets (small Java programs) into a web page.
Applets could display interactive graphics, animations, or run other Java-based functionalities directly within the browser.
However, the<applet>tag is deprecated in HTML5 and should no longer be used — it has been replaced by the<object>or<embed>tag.

</html>Output
Browser Output
There is no visible output in modern browsers because Java applets are no longer supported.
To experience similar functionality, you can embed JavaScript or use the <object> tag instead.

Notes
- The
<applet>tag was officially deprecated in HTML 4.01 and removed in HTML5. - Java plug-ins are now considered insecure and have been removed from most browsers.
- For modern replacements, use
<object>,<embed>, or JavaScript-based web apps.
Conclusion
The <applet> tag was used to embed Java programs directly into web pages but is now obsolete.
Modern web development standards have replaced it with safer and more compatible technologies like JavaScript, <object>, <embed>, or WebAssembly.
