In the correct answer you say that run() method is defined in Thread. But as a matter of fact run() is defined in the java.lang.Runnable interface.
Moreover, "synchronize" is not a keyword, the correct keyword is "synchronized".

run() method is "declared" in Runnable but it is indeed "defined" in Thread class.

The typo with synchronized should be fixed asap.

thanks for reporting!

Yes, you're right! Thanks!
