WORTH NOTING....

If you are learning Java for Android, this solution WILL NOT WORK.

Android (Google) chose to use a different Regex format all together.

This solution will run in JRE and Java online like this, but would not run in the Android Platform.

no problem guys, I won't dare to bore no programming elites here. My deeply excuses.

When you (or someone else) mark it as having spoiler content, only people who haven't completed the kata can't see it. Please, keep your posts (when it's about the same problem) in a single thread.

You did it just below. You asked for help, but nobody answered you. It's no use to flood the Discourse page, nobody is getting paid here. You can try and see if you can find help on the Discord CodeWars channel.

is it possible to ask someone suggestion for my code when I flag it as spoiler? Is there a way of obtaining help here or not? If I post a code shall it be spoilred so that is unvisible? wtf...?

thanks again, yes I've looked into the sorting of strings, but it looks it's not the case for this problem, sorting characters is an inner scale problem instead of sorting a string which contains digits...for me basically this problem is unsolvable, but I am used to think this way, always ;) programming equals to frustration and if sometimes I success it's the exemption, not the ordinary . Anyway thank you again, I appreciate your help, I'll see what else can find and try...

did you try this

thank you for the notice. Apart the spoiler, any comment helpwise to my question?

hi please use a spoiler tag when posting code (I have added the tag)

Ok now I got it...I admit my ignorance and the very seldom use of this kind of notation with three dots "...". Now I understand it is the "Arbitrary Number of Arguments"...
