1>Garbage collection is a deamon thread which runs at the background to support the nin deamon thread.
2>garbage collector is responsible to destroy the useless objects.
3>An obejct is eligible for GC if and only if it doesn;t have any reference.
4>we can also call GC explicitly by System Class and Runtime class
By System Class:
- System.gc();
By Runtime Class
-Runtime r = Runtime.getRuntime(); (here we are creating runtime object by using factory method)
now, you can call gc() method
-r.gc();
