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.
