mysterious Mr. Thread(), Mr. run() and Mr. start()

...and the answer:

(d) The program will compile without errors and will print out |R1b| once and |R2| twice, in some order, every time the program is run.

Why does "|R2|" print if it doesn't have a run() method? or better yet why does it not need its own run() method for it to print out? Why will "|R2|" print out twice? The author says it will print out in some order- which makes me wonder how is it that it can print in random order? I thought the constructors will be used as they appear from the top down like an instance initializer block.

There are some typos and where is R2 defined?
Can you clean up your code a bit? Thanks.

1. You still haven't quoted your source. Please do so.
2. There's a compiler error on line 10


When you do things right, people won't be sure you've done anything at all.
