This MXBean interface allows
monitoring of the number of
garbage collections that have occurred and the approximate time they
consumed in milliseconds. The methods return -1 to indicate that the
garbage collector does not maintain those statistics. Note that VM
implementations commonly have more than one garbage collector and use
different collection strategies for new objects and old objects. Note
also that this is a subinterface of
MemoryManagerMXBean.
