I am playing minecraft and would like to add a "mod" to it, the mod contains .class files which I don't know how to open/run. Right now a program called VLC is trying to open it and VLC is a media player. I looked up .class files on Google and it says it's java. So I would like to know is how do I get java to open all my .class files, and if I can't then what else on my computer can I use ?
I am using windows 7 Home Premium
Also I am very laymen when it comes to computers so if you could help me and not talk "techie" that would be very helpful thanks.
