The real output is error.
"system" must have a capital 'S'.
Aside from that, the output is s.
I assume based on the past comments you actually editted the question, and didn't have the quotes there before.
Without the quotes, nullhello
would be printed.
The reason for this is because it is written in the Source Code to use the value "null" if the string itself is null.
So, you won't be getting any null exceptions for printing things.

nullhello, but if you remove the quotes.
System.out.println("s"); // Gives a String: "s"
