Hello,

All of the examples are missing the last closing bracket at the very end. It should be :

if ( (str != null) | ( i == str.length() ) )
if ( (str == null) | ( i == str.length() ) )
if ( (str != null) || (i == str.length() ) )
if ( (str == null) || (i == str.length() ) )

So correct answer should be all 4!

You are right. This has now been fixed.

thank you for your feedback!
