The other day, I got prompted that a new version of Java was available and I should upgrade. This got me to thinking "what on my system actually uses Java?". As it turns out, nothing that I can find.
So do you really need Java on your system? I uninstalled it several days ago and haven’t noticed anything. If you don’t use anything which requires Java, it does no good on your system so just remove it. After all, you can always easily add it back if you ever need it.
