how to install minecraft on opensuse 13.2

hello, i am new to linux os. i have opensuse 13.2 and i have downloaded the minecraft.jar, and i have no idea how to install it. i am using the kde desktop. i don’t want to dual boot my system since i am trying to get away from windows, and i would hate to have to do a system restore. any help would be much appreciated.

jar files are the Java program

You should be able to run it via command line or menu entry

java -jar minecraft.jar

so put it where you want it to live and then run it
