Why Java???

Question

please I don't know Java stop challenging me in Java try Python

Answer 1

Anybody can challenge you in any avaliable language, as long as you have the course selected. To stop people challenging you in it, go to your course, and click on the icon of the language that you are currently learning. This should take you to a list of languages. Tap the three dots next to Java, and click remove course.

You are now no longer 'learning' Java, and no one will challenge you in it. If you have any progress, it will be saved.
Keep on coding :D
