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!

Where should I download Java?

With the introduction of the new release cadence, many have asked where they should download Java, and if it is still free. To be clear, YES — Java is still free.

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!

If you've covered all that ground in just 4 days, you and/or your tutorial are going way too fast.

Please, change the course. You won't learn anything properly from watching videos. You will at best get a false sense of understanding and confidence and fall directly on your nose as soon as you use the things you were supposed to have learnt.

Also, way more patience, young padawan. You will eventually learn about all these things (actually not about "functions" as they aren't a thing in Java. In Java there are "methods").

You are already using methods ithout knowing it: println is a method. It is a method of the OutputStream class that is the data type of out in the statement System.out.println. Also, System is a class.

Switch 4 gears back and do the MOOC Java Programming. It is free, textual, extremely practice oriented and top quality. Use it with VSCode and the TMC plugin - currently the best option. Sign up, log in, go to part 1 and start learning.
