    Is it important to download JDK?
    Community Answer
    You only need to download the JDK if you are looking to develop or debug Java-based software. If you're just looking to run Java applications, the JRE is enough. You get the JRE by normally installing Java.

    What do I do if it keeps coming up with the coding text box?
    Community Answer
    If it's in the installer, redownload the installer. If the installer works, download jarfix.

    I’m trying to download Java to install Optifine. When I try to open the Optifine file, it says Java isn’t downloaded when I did all these steps. What do I do?
    Community Answer
    Is Java on your desktop? if it isn't, try restarting your computer. It should be on your desktop after you restart.
