when con.close() is executed the memory deallocated in the
server. if we don't use con.close(),connection will be
increased in the server. suppose the connections size are
reached to max connection, nobody access the database in the
site. This is performance issue.

when con.close() is executed the memory allocated for the
connection in the server is deallocated,and the connection
with the client will be terminated.
if we dont use con.close() even if our requirement is
completed,the connection will be remain in the server it is
the more burden to the server,it will kills the performance
