Dear All,
I am a having one doubt while making a connection to a database.
********************************************
// Variables or reference
Connection con=null;
Statement stmt=null;
ResultSet rs=null;
//Db connection
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con=DriverManager.getConnection("jdbc
dbc:abc");
stmt=con.createStatement();
rs=stmt.executeQuery("Select * from <table>");
****************************************************
In this,Connection,Statement and resultset are all interfaces.And moreover,the methods such as createStatement(),executeQuery() are all empty only in Connection Interface and Statement Interface respectively.
Being a method which is defined in interfaces are empty or abstract by default,
if that is the case ,How can we use these here.
(createStatement(),executeQuery())?
Where and all the implementation of these methods..
Pls explain these....
Warm Regards,
Senthan.
