Class.forName attempts to load the class whose name is

representing that class. In the
event that the Class could not be found, resolved, verified,
or loaded, Class.forName
throws one of several different Exceptions

Class.forNmae first loads the class in current classLoader so as to use that in future. Internally DriverManager gets the reference of the driver by using dynamic laoding (nothing is magical) this is is the reason when you say manager.GetConnection() it returns connection using the loaded driver

Hi my doubt is that preparedStatement is a interface means which has no implemenation.plz go thru the code below String sql = "SELECT * FROM movies WHERE year_made = ?"; prest = con.prepareStatement(sql); prest.setInt(1,2002); ResultSet rs1 = prest.executeQuery(); Now setInt and executeQuery how it works since it is interface it does not have implementation how it works, how executeQuery returns result from database as executequery method has no implementation even in Statement interface.
