What is the difference between final finally and finalize




















When you use the final modifier with a method, then it cannot be overridden in a subclass, and when you use the final keyword with a variable, it becomes a constant, i.

On the other hand, finally is a keyword related to exception handling in Java. It's often used with a try block, and it's part of try, catch, and finally trio.

Also, the finally block can be used with or without a catch block in Java, and it's guaranteed to be always executed, irrespective of what happens inside the try neighborhood. This is the reason why the final block is used to do cleanup and free resources.

After the finalize method has been invoked for an object, no further action is taken until the JVM has again determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, including possible actions by other objects or classes which are ready to be finalized, at which point the object may be discarded. The finalize method is never invoked more than once by a JVM for any given object. Any exception thrown by the finalize method causes the finalization of this object to be halted but is otherwise ignored.

Java Differences between final, finally and finalize. The error message is displayed below: The final field JavaExample. Important points: There is no guarantee about the time when finalize is called.

It may be called any time after the object is not being referred anywhere cab be garbage collected. JVM does not ignore all exceptions while executing finalize method, but it ignores only Unchecked exceptions. Usually JVM calls Garbage Collector when there is not enough space available in the Heap area or when the memory is low. This article is contributed by Rajat Rawat and Manav.
