Using 'Character.toString(65)' from the Java.lang.Character combining with Java.lang.Math is my first attempt.
But on some of the computers I tried,
It throws a runtime error: 'Java.lang.Character does not contain the specified method toString'
As I am not allowed to make much changes on those computers,
is there any way to generate random characters [A-Z]?
Thank you very much.
