threads??

[srikanth reddy]

 Which of the following statements about threading are true
 
1) You can only obtain a mutually exclusive lock on methods in a class that extends Thread or implements runnable
2) You can obtain a mutually exclusive lock on any object
3) A thread can obtain a mutually exclusive lock on a method declared with the keyword synchronized
4) Thread scheduling algorithms are platform dependent

fnrds,
i have a doubt here...the answer for the above one is 2,3,4...
2 is fine..
in 3 dont u think mutually exclusive lock on a method is wrong and instead should be mutually exclusive lock on a object..
and in 4 platform dependment means JVM implementation dependent ..

thanks
sri

Sorry, it is too subtle for me. The "method" could be part of the phase "declared with ...". And in many cases, "platform" and "JVM" is interchangeable. Definitely more of a discussion for lawyers...
