The Garbage collector of JVM collects only those objects that are created by new keyword. So if you have created any object without new, you can use finalize method to perform cleanup processing (destroying remaining objects).
Garbage collection is performed by a daemon thread called Garbage Collector(GC). This thread calls the finalize() method before object is garbage collected.
In java, garbage means unreferenced objects.
It makes java memory efficient because garbage collector removes the unreferenced objects from heap memory.
t is automatically done by the garbage collector
a part of JVM
The finalize() method is invoked each time before the object is garbage collected. This method can be used to perform cleanup processing. This method is defined in Object class as:
The gc() method is used to invoke the garbage collector to perform cleanup processing. The gc() is found in System and Runtime classes.
Neither finalization nor garbage collection is guaranteed.
