Thread: How we are able to access the createStatement(); method

Connection con = DriverManager.getConnection(..................);

*Statement st = con.createStatement();

*Connection,Statement are interfaces and all the methods are abstract methods. Then how we are able to access the createStatement(); method (which is an abstract method) , since we did not provide any implementation in subclass nor implemented Connection interface. How can we use the methods.

Question asked by visitor Sudheer Martha

DriverManager.getConnection() returns a concrete implementation of the Connection Interface.

Similarly, calling createStatement() on the connection object (the concrete connection implementation) returns you a concrete implementation of the Statement.
