In reference to this question: How to make java wait for user input?
Apparently, it was unknown or forgot to add 4 spaces before the first line. Which makes the source code unreadable because there are no linebreaks anymore.

Oops! Your edit couldn't be submitted because:
Edits must be at least 6 non-space characters; is there something else to improve in this post?
What to do at this point?
