Why can't i use statements like

Question

c:
delay(1000);
or
java:
try{
Thread.sleep(1000);
}
catch(Exception e){}

in soloLern apk

Answer 1

SoloLearn doesn’t support a dynamic console, the code and input gets sent to them, it’s compiled and run there, then output gets sent back.

This is also why input is at the beginning and there is no graphics besides web.

Answer 2

because sololearn playground is a 1 shot. The same reason all input needs to be put in before it runs.
