Answer 1

You can open JMC and check for GC under Memory tab inside MBean Server of the particular JVM when it performed and how much did it cleared. Still, there is no fixed guarantee of the time when it would be called. You can initiate GC under Diagnostic Commands on a specific JVM.

Hope it helps.
