The correct operator is "!=", not "==". You should to use "str != null" because if str is null "str.length()" will throw NullPointerException. Thanks for notice! Sorry, my mistake.

The correct operator is “!=”, not “==”. You should to use “str != null” because if str is null “str.length()” will throw NullPointerException.

Thanks for notice!
