Hi, looks good, interesting way to learn about Java. IMHO it would be nice, if there were more space for user input (choosing from two options is not enough). Questions at the end are good example for adding user interaction, not just only revealing the answer.

There is something strange in 03-04, second line starts with "6 myBoolean ...". I don't understand it.

Also at 03-13 is incorrect result, it's false.

Anyway, looking forward for PHP. ;)

Thank you for those suggestions; they're great! The tutorials are definitely going to get more options and the questions at the end of each chapter will become way more interactive in a future update! The 6 in 03-04 should be "boolean" and you're right about 03-13. Again, thanks! :)
