public interface Driver
DriverManager
in
a static initializer.
Because the DriverManager
might attempt to use several
drivers to find one that can connect to the requested database,
this driver should not cause large numbers of classes and code to
be loaded. If another driver is the one that ends up performing the
request, any loading done by this driver would be wasted.
