why does my java code run in eclipse but not as an .exe. or .class file

Question

I have this cool program that I wrote in java using eclipse. When I run it in eclipse it works exactly as it's supposed to. I exported it as a jar file so I could use Launch4j to convert it to an executable file(.exe file extension) which I did successfully, but now when I try to open the executable it says the program is incompatible. i tried compiling the code at command line and when I typed "java Calculator" to try to run the program and it worked perfectly. So my question is why won't the executable work? Any help would be greatly appreciated. The source code is displayed below in its entirety.

Is there a reason it needs to be a .exe instead of an executable jar? If you are not sure, look here http://www.excelsior-usa.com/articles/java-to-exe.html It ran for me as an executable jar with no problems.
