Understanding runFinalization()

The runFinalization() method is a part of the Runtime class, and its purpose is to trigger the execution of the finalization methods of any objects that are awaiting finalization. Its sentence structure is as follows:

public void runFinalization()

In Java, every object has a method called finalize(). Before reclaiming the memory that the actual object was exploited, the garbage collector calls this method. It provides an opportunity for an object to perform cleanup operations earlier than it is garbage collected.

However, the execution of finalize() is not secure, and it depends on when the garbage collector decides to collect the object. Sometimes, Garbage collection may not occur immediately in all cases, and as a result, the finalize() method might not be called promptly.

This is where the runFinalization() method acting comes into play.
