why got this java.lang.AssertionError: Only one semicolon

I really couldn't imagine that this Kata is that level of a pazzle. It seems like a hidden bonuce quest about the Java language understanding.
I dont think that all the responses were helpful, but thank you anyway for spending time to answer me. ... and yes, I got through. :)

Read the statements that you find

Well, the 1 semicolon limit includes the imports too

Now focus on this part

Well, the 1 semicolon limit includes the imports too

Now add the semicolons of the imports with those of your code

1 + 1

Notice that the result of the above expression is not in your favor

import java.util.stream.*;

Isn't that a semicolon?

you have TWO semicolons, please limit it to ONE.

we need at least one for the return expression.

That's why you get the 1 semicolon :P But that's it.

Can it be clarified? How can we write Java code without any semicolons? we need at least one for the return expression.

All non-lazy solutions are invalidated and no new have appeared in the meantime so issue seems sufficiently fixed.

This following code has only one semicolon ignoring the imports,

Well, the 1 semicolon limit includes the imports too. It's not really a kata issue.

Another one string solution ^^. Good choice.

Thank you. I have enjoyed solving this kata.

thanks,
the example shows that extention methods contribute a great deal to the readability of code.

I'd ask one question to author - WHY...why? =))) Thanks for good idea and challenging Kata!
