It seems as if the reason you’re getting an error is because the userReadables is initially set to a null string. in the catch, you have
catch(Exception e) {
userReadables = null;
}
and since the userReadables is already null, it’s calling the Exception before it does anything else. Make it something related to the program. Change it to
String userReadables = " ";
that way it will at least be registered as a space, and not null.
Hope this helps!
