Can we use RxJava on SoloLearn?

Question

I recently knew about RxJava and its features.It is a great library for reactive programming on JVM-based languages like Java,Kotlin,etc.
Now I want to know that can we use outer libraries like RxJava in SoloLearn Playground?

Answer 1

Just try it out yourself. If it works, the answer is yes. If not, the answer is no.
I don't think you can use external libraries for non-web languages in the Code Playground.
