Garbage Collection

I have read in some places that Garbage Collection in java cannot be forced. If this is true, what does System.gc() do?
What does Runtime.gc() do?

System.gc() or Runtime.gc() simply make a tentative call to run the garbage collector. They do not force at all the garbage collector to be run. Thus the garbage collector may or may not run, but you can never be sure

a small correction ... that would be Runtime.getRuntime().gc()
this is because gc() is not a static method
