How to detect Java SoloLearn Playground in code?

Question

Are there any hack to detect if we are executing our codesbits in the SoloLearn sandbox?

I attach some research about that using system environment vars

Answer 1

The only thing that hurts my feeling whenever I run someone's python or java codes is that clueless pop-up that aways shows - saying "
LOOK LIKE YOUR PROGRAM NEEDS INPUT.

(I believe the user used an input or scanner ) but this SL pop-up doesn't come with a good hint.

Sometimes I enter a string and got an error message, while other times I enter an integer while it was supposed to be a string.

Web dev playground is still the best in SL
