Resources for learning Java

Java Discord server (unofficial)

  • No JavaScript. Please use /r/javascript instead.
  • No links to your stackoverflow questions - we are not a second opinion to stackoverflow, nor are you going to get answers here when you didn't get satisfying ones there.
  • No Rewards: You may not ask for or offer payment when giving or receiving help.
  • Help on how to post code
  • Do not reply with complete solutions, rather comment explanations and guides. Comments with solutions will be removed and commenters will automatically be banned for a week.
  • No PM help requests. Either ask your questions here and show your code, or you're out of luck. PM help requests will be removed without warning.
  • No piracy! We do neither tolerate requests for pirated material, nor do we allow advocating pirated material (even mentioning that you could download commercial products for free is forbidden) - such content will be removed without warning and the poster will automatically be permanently banned from the subreddit.

  • 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.
    • Ideone for executable code snippets that use only the console
    • Google Drive, Dropbox, Mediafire, etc. are not suitable for code posting!
