Difference between final, finally, finalize


Difference between final, finally, and finalize:
Final:
• The final is the modifier applicable for class, methods, and variables.
• If a class declared as the final then child class creation is not possible.
• If a method declared as the final then overriding of that method is not possible.
• If a variable declared as the final then reassignment is not possible.
Finally:
• It is the block always associated with try-catch to maintain clean up code which should be executed always irrespective of whether exception raised or not raised and whether handled or not handled.
Finalize:
• It is a method which should be called by garbage collector always just before destroying an object to perform cleanup activities.
Note:
• To maintain clean up code faunally block is recommended over the finalize() method because we can’t expert the exact behavior of GC.
