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. ;)

If you like this environment, https://www.codecademy.com/learn already has a php course.

This looks great. I have a few friends involved in teaching K-12 education who have been exploring ways to introduce some of the younger ones to programming so I will be sure to pass this along.

Great! The setting should definitely work with K-12 kids. Thanks a ton! :)

Great job with your app! I'm enjoying playing with it. Java was a wise language choice given it is the language used by AP Computer Science A courses. I hope you will consider Javascript next, the Github code rankings show it as the most popular language: http://www.wired.com/2015/08/github-data-shows-changing-soft...

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! :)

Thanks so much for your feedback on Javvy! Yes, Javascript: it's going to happen! By the way, in this article I cite Java as the most popular programming language (based on the TIOBE index): https://medium.com/@hellocode/getting-javvy-or-how-we-re-bri...

Interesting concept. I especially like that you've made it a little bit more fun, which could make it more accessible. If I'm not mistaken, these are bite-size tutorials? Will it lead eventually to a finished program? Building something that worked and was function/moderately useful was what perked my interest to dive further into development.

Thanks! Accessibility is still a big issue and I think that, yes, bite-size tutorials like ours are a great way to lower the "barriers to entry" - especially for non-technical people. The relatively small screen size of phones has an impact on the functionality of the programs we can show in Javvy but we're getting there!

I teach a beginning Java course at the university. I told my students to install your app... Apparently it's not free after a point... if you need testers, I have 40 students that are available.
