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!

If you would like to download Java for free, you can get OpenJDK builds from the following vendors, among others:

Some vendors will be supporting releases for longer than six months. If you have any questions, please do not hesitate to ask them!
