You can directly run the GC whenever you want to ?????

true or false ?

Hi, I guess its false, At the most u can make an object
'eligible' for g/c.But whether/when the object will be
g/c'd is the prerogative of the jvm and not the programmer.
Plz. correct me if i am wrong.

thanks kiran, one of the mocks said it was true though so i just wanted to be sure ...

You should note that you can call it directly by writing System.gc(). But this doesn't gurantee that the objects no longer in use will be collected. So the answer is true according to Khalidp.255 "The System.gc() method can be used to force garbage collection.."

Hi, u can't run garbage collector whenever u want to. U can just put a request that u want the garbage collector to be run, it is then upto the JVM to run the garbage collector depending on the priorities of the jobs it has to do, so that running gc does not affect the performance of ur program. So u can not be sure whether unreferenced objects will be garbage collected or not.
