Explanation/Reference:
Explanation:
In previous versions (prior to 4.0) of JDBC, to obtain a connection, you first had to initialize your JDBC
driver by calling the method Class.forName. This methods required an object of type java.sql.Driver.
Note:
DriverManager: This fully implemented class connects an application to a data source, which is specified
by a database URL. When this class first attempts to establish a connection, it automatically loads any
JDBC 4.0 drivers found within the class path. Note that your application must manually load any JDBC
drivers prior to version 4.0.
