what are the limitations of the code playground?

Question

is there a list of the imports that will work for say, java? does everything have to be written in the same class? is OOP possible with the use of access modifiers? can there be any gui implementations?

Answer 1

You can only run console applciations for non-Web code and all inputs must be provided in one go separated by new lines. 😉

Answer 2

one thing is that you can't take input at runtime
