final:
final keyword can be applied to vairables,method,class.
fianl variable - You can't reassign/modify values to the
vaiables.
final class- You cannt extends(inherit) the class.
final method- You cannt override the final methods.
finally:
finally is used in try-catch (i.e exception handling in
java).
Each try contain only one finally blocks not more than
one.
There is no statement between catch block and try block.
It will be execute if exception is occure or not.
Mostly used for memeory release.

Answer / ranganathkini
When a class is marked final, it cannot be subclassed. When
a method is marked final, it cannot be overridden by the
subclass. And when a field is marked final, its value once
set, cannot be reset.
finally is the last clause in a try...catch block. It is a
block of statements that is executed irrespective if or if
not an exception was caught in the preceding try block.
finalize is a reserved method in Java, which can be
overridden by classes containing code to release any
expensive resources being held to by the object. Expensive
resources include, native peer objects, file/device/database
connections.
