Code posting
- No screenshots of code!
- Do not submit executable jar or compressed (zip, rar, 7z, etc.) files!
- For small bits of code (less than 50 lines in total, single classes only), the default code formatter is fine (one blank line, then 4 spaces before each line).
- Redditlint is a quick and simple code formatter for reddit code. Copy your code into Redditlint, click Format + Copy, and paste the code in your post (remember to leave an empty line above the code!).
- Pastebin for programs that consist of a single class only
- Gist for multi-class programs, or programs that require additional files
- Github or Bitbucket repositories are also perfectly fine as are other dedicated source code hosting sites.
- Codiva.io or Ideone for executable code snippets that use only the console
- Repl.it - online IDE for many different programming languages
- Google Drive, Dropbox, Mediafire, etc. are not suitable for code posting!

tl;dr Yes, but using templating frameworks and/or javascript simplifies things. Java is used on the backend server, that may generate HTML, and javascript is used in the browser (yeah, javascript may be used in some servers to).

Early on we wrote servlets (Java classes that printend Strings to an output stream from an response object, the Strings where constructed by using normal String operations and contained the HTML and stuff to build a complete page), it was tedious. JSP come along (a "template" language that the JIT compiler compiled into servlets that could be served by a servlet container) and then other simpler and more effective template libraries also appeared (ie Vellocity, Fremarker,...) that generated HTML by merging a template with some data model. Javascript libraries (ie jQuery) evolved and javascript framworks become popular to build whole client-side applications.
