public class Garbage
{
int a=0;
public void add()
{
int c=10+20;
System.out.println(c);
System.out.println(a);
}
public static void main(String args[])
{
Garbage obj=new Garbage();
System.gc();
System.out.println("Garbage Collected");
obj.add();
}
}
Above is a code in java used for garbage collection. object
obj has been created for the class Garbage and system.gc
method is called. Then using that object add method is
called.System.gc method if called the obj should be garbage
collected?

First We cannot force the garbage collection to garbage the
object. Garbage collection can never be forced.
So by calling System.gc() will not ensure you that the
object will be garbage collected.

Garbage Collector is called by the JVM. and it will collect
the objects which has no reference, in the above case obj
has reachability,so JVM won't force the garbage collector to
collect the obj object.

Maverickhari,
Garbage collector is system created thread which runs
automatically.
We are not sure when the garbage collection is going to
happen. this totally depends upon the JVM. Like connection
pool all the the objects are created in pool JVM will check
if there is no free memory in pool then it searches for the
objects which are no longer in use and will garbage collect
that and allocate to some other object.
hope this will clear

Java provides us one method System.gc()to call garbage
collection forcefully.But by calling System.gc() will not
ensure you that the object will be garbage collected.
