Answer / niraj talukdar
Garbage Collection is an automated process in Java unlike C
and C++. It executes to wipe out those objects which no
longer are used in a program or stay idle for a very long
time. This to free memory space alloted to these
objects.However, it is not guaranteed that all the idle
objects wil be destroyed every time garbage collection
process gets executed.A user can also manually call the
garbage collection to take place by executing System.gc()
method.

Variable/object

to it.
2. Is eligible when its reference is set to null i.e
objName=null.
3. referred by method variables or local variables are
eligible for garbage collection when they go out of scope.
