exception handling finally block in java code example

Example: importance of finally block in java

Finally block is used for cleaning up of resources such as closing connections, 
sockets etc. if try block executes with no exceptions then finally is called 
after try block without executing catch block. If there is exception thrown in 
try block finally block executes immediately after catch block.
If an exception is thrown,finally block will be executed even if 
the no catch block handles the exception.
