sorry i didn't say or ask anything and just translated, that was because it had one of the default js kata templates in them for a very basc kata. This may have come around when you were in the javascript language and clicked insert example kata or something. I've translated the kata to the best of my ability to be as close to your java version as i can, hope it helps :)

I don't know more than you:-( Do you print the input and your output to see what happens?

Please could you post exactly between backticks what you get from the test?

Hello, World! is not a greeting... is a pretty weird imprecation, please don't use near any other human ( or near any planet ). In other topics I've updated description. This is the very first program that checks for the output in codewars. Enjoy!
