I have a gigabyte worth of Java files on my computer that I don't think I need. They come in three flavors:

  1. /Users/Me/Library/Application Support/Java/Java 8 Update 66.app

  2. /Users/Me/Library/Application Support/Java/Java

  3. /Users/Me/Library/Application Support/Java/Java 2/JavaAppletPlugin.pkg

From what I know, .pkg files (and maybe .dmg files) are only used for installation, so I don't need them. Also, I think I only need the most recent version of the .app file.

Will someone stop me before I shamelessly delete all these files? (Which of these files can I safely delete?)

    hmmm... prompted me to have a look... 14 distinct versions, 1.44GB. Does seems a bit of a waste of space.

The java installation/update files in your home Library folder are safe to delete. Especially the specific ones you are listing.

Anything under /System/Library/Java/ or /Library/Java is probably better to left alone unless you know what you're doing or use a officially documented uninstall procedure.

edit: If an application will need to have java installed (i.e. happened to me with an old adobe program) you can install it again!
