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
The right answers are 2, 3, 4
I would like to know why answer 2 is right as i feel that u need to have snchronized method or code to get a lock.
thanks
