As far as I know, the built-in class java.lang.Thread is the only game 
in town.  The JVM is responsible for implementation, it will use 
pthreads or native processes or whatever is considered "best" on a given 
platform.  (Did you really mean "libqthread" or "libpthread"?)

Java doesn't do "special libraries on each platform" like C does.  Java 
puts all its effort into making the one implementation there is be as 
fast and as efficient as possible.  That's a bit of a change of mind-set 
for a lot of folks, but it works very well in practice.  I'd do some 
bench-marking first before you decide to try to import special libraries.

There are of course libraries in the Java API.  Be sure to check out the 
java.util.concurrent package.  Actually using Thread directly is 
considered noobish these days.

Here's a primer:
