What happens when exception is thrown by Finalize method?
If an uncaught exception is thrown by the finalize method, the exception is ignored and finalization of that object terminates. Any exception thrown by the finalize method causes the finalization of this object to be halted, but is otherwise ignored.
What is the purpose of finalize () method?
The Finalize method is used to perform cleanup operations on unmanaged resources held by the current object before the object is destroyed. The method is protected and therefore is accessible only through this class or through a derived class.
What is the purpose of using finalize method What is garbage collector in Java?
The finalize() method of Object class is a method that the Garbage Collector always calls just before the deletion/destroying the object which is eligible for Garbage Collection, so as to perform clean-up activity.
What would happen if an exception is thrown by the Finalize method Mcq?
Explanation : When Garbage Collector calls finalize() method on an object, it ignores all the exceptions raised in the method and program will terminate normally.
Does System GC force garbage collection?
gc() method runs the garbage collector. Calling this suggests that the Java Virtual Machine expend effort toward recycling unused objects in order to make the memory they currently occupy available for quick reuse.
What is Java garbage?
In java, garbage means unreferenced objects. Garbage Collection is process of reclaiming the runtime unused memory automatically. In other words, it is a way to destroy the unused objects.
Why Finalize method is protected?
The finalize() method is not public because it should only be invoked by JVM and not by anyone else and protected so that it can be overridden by the subclasses.
What is the use of Finalize method in C++?
Finalize is an object method that contains the code required to free unmanaged resources and perform cleanup operations prior to garbage collection (GC). The finalize method is used to clean up resources not managed by .
What is garbage collection What is the difference between garbage collection and finalize () method?
gc() cleans up memory, and uses finalize() to get rid of the individual objects. Garbage collector is invoked by calling the System. gc() method on any class. But it does not guarantees that all the nullified objects will be garbage collected before jvm shuts down.
What do you mean by garbage collection and finalize method?
The task of garbage collector thread is to sweep out abandoned objects from the heap memory. Abandoned objects or dead objects are those objects which does not have live references. Garbage collector thread before sweeping out an abandoned object, it calls finalize() method of that object.
Why finalize () method should be avoided?
“This method is inherently unsafe. It may result in finalizers being called on live objects while other threads are concurrently manipulating those objects, resulting in erratic behavior or deadlock.” So, in one way we can not guarantee the execution and in another way we the system in danger.
Which of the following blocks will be executed whether an exception is thrown or not?
statements in the finally block
Explanation: The statements in the finally block will always be executed, whether an exception is thrown or not.
