What will happen when you attempt to compile and run this code?

1) Compilation and output of count from 0 to 99
2) Compilation and no output
3) Compile time error: class Runt is an abstract class. It can't be instantiated.
4) Compile time error, method start cannot be called directly

Well, I guess this should've been none of the above because technically speaking Runt is all but abstract. Here's the compiler error:

You're right, Vad -
There's no implementation of run() in Runt, so it must be declared abstract (which it isn't). I can see where the author may say that (3) is correct, except for the missing abstract declaration.
Correct answer: none of the above.
Good catch!
