can someone tell me how does preparedstatement works? its
an interface and where is the implementation?

Answer Posted / sk.bilal ahmed

A SQL statement is precompiled and stored in a
PreparedStatement object. This object can then be used to
efficiently execute this statement multiple times.

Note: The setter methods (setShort, setString, and so on)
for setting IN parameter values must specify types that are
compatible with the defined SQL type of the input
parameter. For instance, if the IN parameter has SQL type
INTEGER, then the method setInt should be used.
