I had an issue where whenever I tried to run Java files, it simply wouldn't run. I was recommended to try to re-associate .jar files with Java Runtime Environment, because .jar can be opened by other applications, which might be why the Java files weren't running. I used Jarfix for this and it solved that problem really well, so if you have this same problem, I recommend using this tool, and it's free too.

Instead of working around it, you can use this "light" software that can help change the little things that matter rapidly.
