Garbage collector is used to collect those objects in the Heap memory which is not referenced by any reference variable by calling System.gc() method. The purpose of GC is to delete objects that can't be reached. Only the JVM decides when to run the GC, you can only suggest it.

Garbage collector removes those objects from heap memory which are no longer referred by any other objects.Using System.gc() you can call garbage collector but its not neccesary that it will run.JVM decides when the Garbage Collector will run.
