Answer Posted / anand
We can not create object to any interface but we can create a reference variable to interface. Connection is an interface released by SUN micro system.Once interface released anybody in this world can provide implementation,provide implementation means writing down the code for all the methods of that inteface. As we know that Connection is an interface relased by sun micro system and Oracle corporation provide implementation class to that inteface and this class is called "Connetion class".We can create the reference variable to Connection interface and this reference variable hold the object of class which provide the implementation to Connection class.
DriverManager is also an interface and this interface contains a static method getConnection(), this method returns the object of a class which provide implementation of Connection interface.
