of driver class i.e
static
{
try{
DriverManager.registerDriver(new Driver());
}
catch(Exception e){}
}

what does the method Class.forName returns?..

Answer / uv

When Class.forName("<classname>") function gets
executed,the class gets loaded in JVM.

To create an object and access its functions and variables,
we can use getInstance( ), please look into the below
fragment code:

Class c = Class.forName("Cls");
Object o = null;
o = c.getInstance( );
// type casting the Object
Cls cl = (Cls) o;
