Answer / muffy.jad@gmail.com
The finally block is used to ensure resources are recovered
regardless of any problems that may occur.
finally is important because it allows the programmer to
guarantee the release of memory regardless of what happens
in the try block
finally is necessary when you need to set something other
than memory back to its original state.

Finally block always execute, its not consider whether an
exception is raised or not. Once try block is executed
means finally will be executed.
Finally block is necessary, often sufficient to execute
some important things its nothing but connection close
stmt..
system.exit(0); given in try catch block means finally
block will not be executed.
