Sorry for the delay, however I didn't find it even though I search for something similar, what should I do in this case?

Un-publish?

Cause StringBuffer is thread-safe and used only if you have multi-threading programm and need synchronisation. So, it's work slower that StringBuilder. In this case there are no reasons to choose StringBuffer, cause we have just one thread.

A broken egg is, obviously, broken, so you can't use it again.

I don't understand if I can throw n eggs at every try or not.
So let's suppose I throw 2 eggs and just one cracks, next try I have 2 eggs again or just one remains?

It's a nice kata, I just want to provide a similiar kata, fortunately I find this in advance.

I like it, thanks

Pls feedback!
Is it too easy or too difficult?

Ahahahahah man good job,
You actually cheated!! I wanted you to use the reflection O.O

Oooook thanks to you trick, I changed it. Now should be shielded from you code.

StringBuffer is slower, so if you don't need synchroniszation/parallelism, you should prefer StringBuilder.

Efficient is good enough, so I can use StringBuffer.

Why StringBuffer and not StringBuilder?
