How will I be able to add Java into an HTML document?

Question

We can add other programming languages such as CSS and JavaScript, which are the building blocks of webpages, but what about other languages like Java?

Answer 1

You can add Java to HTML using Java applets.
About alone Java, or next languages. The only what support web browsers inside are HTML, CSS and Javascript. There are some other script langauges, or extensions, or frameworks. to add into HTML, but you must add their support into HTML to download their libraries..

Answer 2

HTML5 is made up of CSS, HTML, and javascript. You can add CSS to your page by adding <style> tag to the head section and javascript to the head or body section by add <script> to your html document.
Even though you can add all three to your html document, it is really better to make each its own document and link it in the head section.

Example:
Style.css
Index.html
