What does it mean when you have this in your folder?
I used to ignore the first one but I saw a fully working jar file with all ten ...$10.class inside. So now I am wondering if it is necessary to include all of them in my jar file 'coz until now I haven't made my works jarred and working. I have them jarred but working no.There is always an error. Thanks!
