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.
