what does the method Class.forName returns?..

Answer / m.gangadhar

Example
Class.forName("oracle.jdbc.driver.OracleDriver")

first it loads th class name at run time
second it executes the static initializer containg the code
of driver class i.e
static
{
try{
DriverManager.registerDriver(new Driver());
}
catch(Exception e){}
}

then it creates the object for the driver class and
registers that object in to the DriverManager

Answer / priyank jain

Static method Class.forName(String className) returns the
Object for the classname specified in argument passed to
method.
Also Class.forName used to load drivers.
Ex. In JDBC call
Class.forName("org.apache.derby.jdbc.EmbeddedDriver");
automatically creates an instance of a EmbeddedDriver and
registers it with the DriverManager.

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;
