Closing a Connection

After you complete required data operations in the database, close the database connection.

You can call the close method to close the connection.

conn.close();

Many database classes such as Connection, Statement, and ResultSet have a close() method. Close these classes after using their objects. Closing Connection objects is to close all the related Statement objects, and closing a Statement object is to close its ResultSet object.
