Statement, PrepareStatement and Callable all these are
interfaces. Thought it is a interface how come we are
creating objects and calling methods("preparestatement()")
in it. In which class this method is defined.
Please let me know. Thanks in advance.
example:
PreparedStatement pre = con.prepareStatement(
"UPDATE COFFEES SET SALES = ? WHERE COF_NAME LIKE ?");
