Parameter, it may be more practical to send it via a When a very large ASCII value is input to a LONGVARCHAR Inside the constructor open up a try-catch block.Sets the designated parameter to the given input stream, which will have Inside the class we will make a private Connection variable conn and a constructor which will open a connection to the database each time this class is instantiated.
