kata hint != kata suggestion

Approved

Thanks! just reailzed what i did wrong

fixed

Hint: Don't forget to check for bad values like null/undefined

the array may contain null values in Java

Umm I cant see if others have marked this as an issue because I can't complete the kata, but in java whenever atempting to complete the challenge I got this error code, "java.lang.Boolean.booleanValue()" because "[]" is null

И что же значит null/undefined? Может стоит описать, что мы делаем в таком случае? Так, на всякий случай

not working i test my code in irb console it work correctly but my code is not read as it is.
