1) b. Higher priority stuff is usually run first, or gets more CPU time, but it depends on the implementation.
2) What is java_g ?? I didn't see anything about this on the exam.
3) false. Garbage collection might have some rules in the JVM (I don't really know), but the actual implementation can varry a lot.
4) c. Instead of getHashcode(), it's hashcode().
5) a. sleep() is the only method in the list that is a member of Thread.
6) Never heard of java_w

Where are you getting this stuff?
