when the Class.forName("oracle.jdbc.driver.OracleDriver) is
executed, the driver calss will be loaded if it was not
loaded earlier. As soon as the class is loaded the static
block will be executed. In the static block the JDBC driver
vendors are responsible for providing the static block in
the driver class. In static block they would have been
written the similar kind of code.

public class oracle.jdbc.driver.OracleDriver implements
Driver
{
static
{
Driver drv= new oracle.jdbc.driver.OracleDriver();
DriverManager.registerDriver(drv)
